I really love a lot how she turned out in your style! As I told you in DMs I love how you managed to catch her curious look and the choice of giving her big, round eyes with small irises enhance it!
Another thing I truly appreciate is your effort to draw something that was out your comfort zone: animals and more specifically a feathered coelurosaurian theropod dinosaur. Coelurosauria is a clade containing all theropod dinosaurs more closely related to birds than to carnosaurs.
Birds on the other hand are feathered theropod dinosaurs and constitute the only known living dinosaurs. Likewise, birds are considered reptiles in the modern cladistic sense of the term, and their closest living relatives are the crocodilians. They are descendants of the primitive avialans (whose members include Archaeopteryx) which first appeared during the Late Jurassic. According to some estimates, modern birds (Neornithes) evolved in the Late Cretaceous or between the Early and Late Cretaceous and diversified dramatically around the time of the Cretaceous–Paleogene extinction event 66 million years ago.
Birds can be quite challenging when it comes to feathers because they have different shapes, colours and patterns and it's the same with feathered dinosaurs. A thing to keep in mind when drawing a feathered theropod is the way wrist are drawn. Raptors are clappers not tappers, this drawing well shows it: https://64.media.tumblr.com/8494c33613d29939ce4b46ec228ab2a9/tumblr_nq08kb3jci1qztb1ro1_1280.jpg

A huge tool I suggest you to use when drawing dinosaurs in general is using skeletal reconstructions because they help you to focus on main elements of the skeletal structure, the body size and proportions. I link here the skeletal reconstructions of Microraptor:
https://en.wikipedia.org/wiki/File:Microraptor_Skeletons_by_Qilong.jpg
My Microraptor OC is based on the holotype IVPP V13352. There are three species of this dinosaur and the first one is not Microraptor gui (the species Xiang is based on) but Microraptor zhaoianus (Xu et al., 2000) while the most recent was M. hanqingi (Gong et al., 2012). But it was the specimen of Microraptor, BMNHC PH881 that helped to discover several features previously unknown in the animal, including the probably glossy-black iridescent plumage coloration.
And I like the technique used to render it, I mean when using a ballpoint pen cross-hatching and gradients are the way if you want to play with iridescence or iridescent-like effects. So kudos to you considering you only used a single colour (black) to render it!
fun fact: in 2010, it was reported that there were over 300 undescribed specimens attributable to Microraptor or its close relatives among the collections of several Chinese museums, though many had been altered or composited by private fossil collectors.
Despite its name Microraptor is not the smallest dinosaur, the smallest dinosaur known from adult specimens which is definitely not an avialan is Parvicursor remotus, at 162 grams and measuring 39 centimetres long. However, in 2022 its holotype was recognized as a juvenile individual. Right now the smallest theropod overall (including avians) is the currently extant bee hummingbird (Mellisuga helenae) at 6.12 cm long and 2.6g for females, and 5.51 cm long and 3.25g for the males.
Anyway, back to the drawing. I like the claw visible in the right wing. Nice job at drawing the hands, they always face inwards, palm-to-palm (remember the clapper NOT tapper thing) and I like how you rendered the tail. Tail is most flexible at the base and didn't wag like I did in my face expressions exercise, that was for comedic purposes. Theropods tails were rigid, long and held straight especially when running, so they weren't used as whips XD
Why weren't theropods tappers (see JP Velociraptors to know what I mean)? Because it was anatomically impossible for dinosaurs to pull off naturally. The wrists would just break if it was tried.
The only thing I feel to suggest when exploring a new territory (i.e. drawing birds/theropods etc.) is to break down the figure into shapes such as circles, squares, triangles etc. This way you can immediately study the overall shape and proportions of the subject you are going to draw. Other than this I commend you for drawing something that is out your comfort zone. Keep it up!
not so fun fact: there's a relatively new yet also well-supported theory on how some dromaeosaurs could've taken down prey, and their wings would've played a very essential role on it. They'd pounce on their prey, hold them down using their famed sickle claws, and stabilize themselves by flapping their wings wildly. After that, they'd start ripping apart and eating their prey and a lot of the time the prey would still be alive.
another fun fact: based on the size of the scleral ring of the eye, it has been suggested Microraptor hunted at night. The discovery of iridescent plumage in Microraptor has led many to question this assumption on the grounds that no modern birds that have iridescent plumage are known to be nocturnal, but this argument is itself questionable as there in fact are modern nocturnal birds with iridescent plumage, such as the kākāpō as well as various night-feeding waterfowl; furthermore, as a forest-dwelling, presumably solitary carnivore, Microraptor was significantly different ecologically compared to extant corvids and icterids with dark, iridescent plumage, which are social omnivores of more open habitats.
