Did two sets of 10 hands from quickposes.com (300 s).

Picrel is the first set.

I was struggling to finish anything at the beginning of the first set but by the end of the second set I was able to do them in roughly half the time (although I do think that some drawings from the first set are better) and I didn't need look at the ref for the most part after analyzing the pose once, which is very comforting.

Yeah my hands still suck but they're better than how I drew before.
