Honestly I feel I'm still bad at painting cause I can't put this kind of quality into imagined pieces, which scares me soo much. All these studies have been from reference so I have a set lightscource, and everything. When I try to match this quality with a figure from my imagination, it does nottt turn out well haha. I'm terrified to post any of those pieces I worked on, but I'll keep trying at it until I have a better understanding of lighting/shading and anatomy!
Oh man, I know how you feel. I keep on trying to be able to recreate stuff done from refrence with my imagination and it's a pain in the ass. You're also far faster than I am at this. Still, great job. I've noticed a lot of improvement anyway.
