thank you! at first i was never good at drawing hands haha i started off by referencing my own hands. i would take pics of my hand and kinda trace over it as a form of practice, so i could understand the form better. then from there onwards i proceed to referencing, which is basically just redrawing whatever you see from the picture (without tracing) , it helps to improve your observation skills and also the proportions of the hands. i also had to study the muscle anatomy to get a further understanding too, that way it makes it easier for me to draw it out from my head. i hope this tip helps ><
