First welcome to Art Portal, second I commend your technique and skills. I checked your Cara account and I've noticed another cool artwork that really caught my interest at checking and voting your work here on NG. I have to say the style is truly pleasant to look at, the light colours and shading are combined in a balanced way that give a videogame artbook vibe. I also noticed you used Krita, that's cool! I use it too and I love how many effect one can achieve, ofc your technique is superior to mine which I have still a lot to learn.
I like the character design of the two main subjects of the composition, it makes them easy to memorize and recognize. But what I love the most is the curious expression of the young girl looking at the lizard on the butler's knee, it's a nice balance between the curiosity typical of young people and inner calm of elderly people. The fact they have bags makes me think they are on an adventurous journey and I image this journey to be a fantasy one or at least the warm colours and lighting give me as feeling.
I really hope to see more Art from you because it's truly beautiful and pleasant to look at. Maybe we can explore the worlds these two are going to visit with your works^^
Keep it up!
