My Concept Arts

Please provide me with feedbacks. Thanks.

Looks alright. She is pretty cute, but I feel the way her face is constructed can use some work. In particular the top middle view in that collage.

agreed, I really like your character, she's super cute
try referencing faces and being conscious of how the simplified style relates to true proportion. it doesn't have to match, realism isn't the goal, but it will help you find aesthetic proportions in the face.

Your colours are great by the way! Show us more!
