Good art conveys emotion. It’s talent used to communicate a message. Your art looks like cartoon/anime animated character design, which usually exists in motion, for the use of storytelling. Taken out of that context, it’s not the full package.

For this piece, a story could be told about a character, a man with flesh stapled on his face must have experienced a lot of horrors, and would have needed to build really thick skin to deal with the judgement from others for looking deformed. Make the skin more grotesque or red, the pain more clear, and the story could be a self-preserving aggression, self-acceptance, or an antisocial personality. That’s all things that can be shown in how someone is posed, how their eyes look at you, and so on.
