hes an illustrator who does drawing classes on youtube, and theyre soooooooo useful! especially his figure drawing playlist, imo
also, for practice sessions i find this site really useful!!
it gives you timelimits and randomly generated poses / expressions / etc based on some guidelines you set, which is great! however... its bank of photos is kinda small, and a lot of the women are very very thin which makes them less helpful to draw.
however the poses at
are great!!! once i got fed up w line of action, but got the hang of their session style, i started using senshi stock for figure drawing practice. realistic bodies, realistic (and fun) poses. also useful references for drawing in general (although if you post drawings that used them as references, be sure to credit them!)
