This is quite the load!! Maybe you can work on different body types and ages/sizes to better diversify? **Forced perspective** would also be a good extra thing to add to the dumps.
Those are good ideas, but most of these are drawn from references rather than imagination. I tend to do 4-7 of these as warm-ups before I start working for real in the day. Still, I should try some from a more extreme perspective and I should experiment more with body types.
Ahh alrighty, warm-ups are warm ups i suppose, I saw these as more of a "practice" thing i guess since that's how must people I know do sketch dumps. Haha. But yeah perspective is super fun. FRUSTRATING AS HELL sometimes, but reeeal nice when it's pulled off just right.
So many poses!
