Thank you everyone for the links, comments, and advice! I read everything you all had to say, saved the references, and it's helped me a lot <3_<3 I hope to have my next sketch up soon, after I finish the hands >.<
[link] is fairly good. The important thing to take away from that is breaking down hands into basic shapes. I find a cube works better than that flat cylinder, but that's just personal preference. Also, PRACTICE PRACTICE PRACTICE. You can use lovecastle [link] and set it to show you photos of hands on a fixed time interval. I'd recommend only 30-60 seconds at first so you learn how to draw the basic shapes of hands, then you can start to increase it when you feel comfortable getting into more detail.
I notice all of your characters in your gallery suspiciously have their hands missing. Draw them! They'll look horrible at first, but you'll never get better at drawing them if you're always finding ways to avoid them.
Also, for some reason a lot of artists (myself included) forget they only need one hand to draw. Conveniently this allows you to use your other hand as a model. Give it a shot!
