I think I have a pretty good hand drawing solution for you.
Your drawings look good so this will be no problem for you.
I use the "Handy art reference tool" when I have problems with hand
poses. I first browse the preset hands and then adjust the angle.
You can move the fingers and wrist in the app. Then I make a screenshot
and trace over the hands with a simple shape. Then I copy the simple
shape by drawing it freehand. Then I draw over the freehand shapes.
I do it that way because I don´t feel good about using traced over references
+ then I make sure to draw it in my style.
It´s really easy once you did it 20 times. This took me 8 minutes and I dislike
drawing hands like everyone else too
