So, I've been looking over a bunch of your art and I must say I'm extremely impressed. You capture muscles and body structure so damn well and can do basically any species, not to mention your shading is absolutely fantastic. The only issues I really notice are hands in some images, which tend to be the bane of every artist in the world (especially me, ugh, hands) though anatomy and the likes? Damn good. I do have to ask what program you use for doodling - Paint Tool SAI, perhaps? Or Photoshop? Do you mix and match between, for shading/coloring purposes? Etc.
Generally, I just have a lot of questions, but wow - this is quality stuff. I'd love to watch you doodle some time if you ever do art streams.
