No paintover, just tipps. If you want to create a design, you need to consider following points: - what is the purpose of the design (will it be used for illustration, animation, game, etc.). The design needs to provide enough information to serve the designated purpose (e.g. for illustrations you will need to create ref sheet for the back and small details as well) - what is character story, environment, what does the character do and how they go about their daily life. Nobody can give make suggestions for design if they don't have any framework for it. For example the hat he has: why does he have it? What purpose does it serve? Does it convey his story? Same for the colors. Lastly, don't beat on yourself - see the things you are unhappy with as an opportunity to learn and improve. You are not happy with this design? Break down in detail what you like and don't like about it. Brainstorm solutions for things you want to improve. That is how creativity works.
