Ways I go about it is, well, I really just uses my own hands as a ref and DesignDoll (
a very nifty posing program by Terawell!) can help a lot whenever it's difficult to pose/hold my hands in a certain way.
Basic rules for drawing a hand is generally:
-fingers are the similar/same length as your palm. Two halves of whole sort of deal.
-hands are usually similar length of the top of your head to the chin.
-start with the basic shapes first. I prefer the square for palms and rectangle for each part of finger(s) and go from there. Some people like triangles and circles instead though, and that's fine. Use whatever shapes that will help you.
Once you get that down, people tends to develop their own rules with drawing hands along the way imo. Some prefers cartoonish hands, some like realistic hands, or in between. It's really worth playing with to suit your needs/wants.
So, all of the suggestions good Dokugians here are pretty good to try, especially the video tutorials. You can get some ideas of how these artists does their hands.
Good luck and hope you can get the hands down soon!
I've a question for Pyreite. You said you did quick gestures, right? And saw improvements in a week? I'm curious, how long did you hold a session in a day? Half an hour each day? I've been thinking about doing them more often, but I have no idea how long I should do it.
Thanks for any reply.
