/ic/ - Artwork/Critique

I'm beg but have drawn for a long time so a moderate beg but with no fundamental foundation.
I've started studying Loomis and other fundamentals so that I can do art professionally someday. But ever since I started using refs and studying anatomy I can't draw from imagination or anime style anymore. It just always looks off or not right, and not because I'm making placement mistakes but because it's not a realistic human face. Can anyone tell me why? I like anime style but I can't replicate it anymore and I don't like how my drawings look right now. Pic related before and after studying. Any info on this phenomenon would be appreciated as well as how I can fix this problem.
