Hello I was lurking in the Review Request Club and I found your work that caught my attention to write down what I think based on what you asked there. But let me first say what I liked and made me want to review this work. I like the colours very much, how bright they are and how catchy to the eyes they are, particularly in the fighting scene where the contrast of them make the visual appealing and this brings to the first thing I want to point out in terms of colours:
in the first three panels the colours of the background is too similar in hues to the purple magician and this makes him blend too much in the environment unlike the blue wizard that stands out nicely. But at the same time I like the sketchy look of the shading because it fits well the style you want to convey with these types of comics. I like it.
In terms of comics readability I didn't find difficult following the scene and pace of narration rhythm. I also find it creative with this use of round shapes instead of the classic rectangular or square shapes you typically find in comics. The font is nice and fits the style of comics overall.
Characters expressions are good enough to make the reader understand what's going on both in terms of scene and character's emotions. A thing I would like to point out though is the way you made the upset/annoyed purple wizard's face in the small panel at the left side of the second main panel (when he discovers the coffee grinds all over the kitchen). The basic emotion can be noticed but the lack of curved muscles around the mouth and eyes wide open makes the face look a bit stiff and I've noticed this in his surprised look when he is about to destroy himself. Maybe instead of putting his eyebrows high, a more irregular shape added to them would have increased the feeling of surprise/astonishment.
I show you how I rendered the face of the purple wizard using Krita:
The red arrows show the tension of muscles and where you have to focus emotion energy when drawing a cartoony's facial emotion. Ofc I am not an expert nor a professional in terms of art but I also think that this website may help you with this element:
This helped me in the past with facial expressions. The blue wizard's expressions turned out good especially in the main fighting scene and in the last panel. You caught well his sense of astonishment and surprise.
When it comes to elements that appear a bit off in my opinion the pose and perspective of the purple wizard's arms during the fighting scene. He looks a bit stiff and gives an overall rigid appearance. This other resource from the same artist I linked above might help you: https://design.tutsplus.com/articles/cartoon-fundamentals-how-to-draw-a-cartoon-body--vector-18651
The blue wizard balances this though. He is drawn in a nice dynamic pose of someone who is about to get hit by the blast.
In terms of comedic value despite probably something I miss that didn't make me fully appreciate it, it made me genuinely chuckle in last part because the overall idea of an exaggerated reaction out of something this mild on the annoying element scale that resulted in something comical at the end is funny to me. Globally I enjoyed this comic, the overall dynamic poses of the wizards particularly in the last scenes, vivid colours and funny characters.
Keep it up and yes, visit Palestine (I've noticed it at the beginning of the comic).
