Along with the advise you already have been given, I wanted to give you a quick process to use to draw your hands in the future. I hope it helps :)

Hi Aaron_1, Yes, I agree with hoda. And I would like to suggest that you also look into perspective drawing, construction, and 3D. In as much as we draw things in 2D space, they should have some sense of form and direction. Your drawing looks flat. It lacks volume. Stan Prokopenko has various free awesome videos on drawing hands on his YouTube channel (look for How to Draw Hands in his Human Anatomy for Artists playlist) that tackle all that I'm writing about and more. If you haven't seen the videos already, I think they are a great resource. If you have them, kindly, be patient with yourself and practice, practice, practice. You are on your way there. And hold on to this drawing and the subsequent ones. And compare your progress after a year. Provided you keep learning and practicing - with more practicing - you will notice significant progress. Good luck.

You should start by studying the anatomy of hands and then copying drawings from others. Paying attention to the proportions is very important. So take your time, measure carefully, and then start. You'll see lots of improvement soon. There are lots of books and YouTube videos that can help you.
