Coming up with interesting, accurate poses for your characters can be difficult. Either they all end up looking the same, or the poses just don't look right. Drawing from a reference is a great way to practice this. Luckily, there are lots of amazing resources available to help you out, both here on DeviantArt and one the big bad WWW. I've listed the ones I know here, so you don't have to do the digging.
- I've picked resources that focus on poses, not on anatomy. This means that the drawn pose references listed here are not necessarily anatomically correct. Though the two are definitely related, to me they're not necessarily the same thing.
