You change the character several times here. At first he is engaged in a kind of fantasy born of his drawings. Then he makes a wish and changes his appearance. Finally, having learned from his experience in another sort of body, he gains confidence and behaves more assertively.
Your story is an exploration, it seems in how our self image affects the way the we behave and the way people react to. This is an interesting story-writing exercise.
Thank you for sharing this story with us. We appreciate that you engage with other writers.
