Very nice studies, keep on pushing and do more of those posemaniacs. I feel your shading is progressing a bit, do you intentionally use only one shadow tone like in those bammes studies? they looked really good but you might try to add lighter and darker shadows as well for experiment
I really like that oil painting of the "little tiger plushie"; it's just really nice to look at, haha. "Swamp" and the studies from this page look great too. I think one thing you need to watch for is the eye placement in faces from your imagination: the eyes often seem too high in these. Good luck!
GusTheRobot, thanks! skintones are indeed hard but so much fun!
Nettle_Mountain, thank you! the Bammes piece are "just studies" and it's hard to make nice subtle shadow variations from photographs :/ hope I can attend life drawing soon, but I'll be on the lookout for nice shadows anyway.
hp, thank you
nolarc, thanks eyes have been mentioned, I'm gonna be more careful there.
