/ic/ - Artwork/Critique

i dont wanna show my coloring, because when i do color, it ends up looking like this. poor shading and borderline flat.

all i wanna know is: how do i STOP and NOT end up coloring like this forever?

preferably, something in video format to teach me? i find they usually go in depth more when it comes to instructions and it's easier to keep up with that than written instructions or pictures.
