having .psd files having layers work together before the final "make image" would help, as an artist i know its dificult but the circles for the anchor points are so big its hard to know where im placing them. possibly adding a option like the puppet pin tool in after effects would help greatly.
this wont work with my tablet (cintq companion) i would need to use a mouse but making it compatiable with my tablet pen could be really cool!
Really neat idea and concept.
