btw, the best tool ever for hand posing is "handy art reference tool"
I use it all the time to pose hands. They have ready to use and turnaround
hand poses, you can modify them in all ways. put shading on them etc.
I take screenshots and then use them as reference. ItĀ“s easier then looking
for hand poses or posing them with your hand.
This is how I use it. I could also trace over the reference but that would 1) feel like
cheating and 2) I want it to be unperfect looking and fitting to my style.
The picture is how I quickly sketched the hand, then what I made out of the reference
