>>44290323I'm far from a good art instructor, but I definitely understand your pain. It took me a while to transition from realism and still life to cartoony monsters. I never dropped my shading habits, but getting better with more ranges of colors and smoother shapes can really help. Trying to replicate the exact style that the official art's drawn in may give you a headache, so it's best to stick to whatever normal conventions you use for coloring and shading at least.
Pic related is a silly little thing I did just last week.
