SHE (still) WANTS THE 3D

[Sketchasaurus]

A huge thing that I see getting in the way is that the broken scratching hinders your ability to feel the broad curves of human anatomy.
Also, each limb is treated as a separate part, whereas they aren't. they flow into each other, muscles overlap and curve along-side each other.
Also, I think using a thinner brush would help greatly, because a lot of features easily get confused when brushes get too big. Also, pen tablet pressure really helps sketching things out (though my driver was being uncooperative while I was sketching around here.)

ALso, when drawing T-poses, a more relaxed pose than the rigid T is often preferred. while having the arms outstretched is easier to rig, they don't have to be all the way up like that.
