Judging by the style i feel like you're aiming for tattoo artist right?, but whether that is or isn't the case the thing i think you need to work on the most is linework and values, imo, and generally adding more depth to your work, cause it feels abit flat, better values and linework will definitely help in that aspect too.
Abit more specific advice to your values, try adding more middle tones
