gasp.......... clever
ive considered stuff like that actually, its nice, natural. back when i studied theatre the actors used to lounge about in place a lot while the director gave instructions, i got some great drawings of them. dancers too! dancers are the best! i could organise a deal with the dance students at college, were in the same block and pretty friendly. double win, bc i love watching dance (and dancers are very very attractive, wholesale)
that said, actual life drawing sessions have the benefit of being able to ask someone to stay in place for an exact period of time, chasing after a pose before its gone can be stressful
