You do amazing in pencil, ( I tend to do pinups only). As for hands, I hate them, I had a teacher who made us draw 15 different ones, and then one big set of them, prob was the only thing the teacher did right ( this "teacher" was horrible if she did not like your subject you did poorly grade wise). Best advice I can give you is just draw them alot, and if ya mess them them up do better next time, yours arent bad so I would not worry about it much, I tend to draw 3 sets then kinda import the ones I like into the finshed piece. GL and keep up the good work.
