As you may or may not know, I moderate a section at drawingboard.org called the Drawing Jam. It's a place where I post figure reference images every month or so and everyone does their take on the subject matter. Some people do straight figure work, some stylize, and some get really creative. Many of my best drawings are from these sessions, and there are tons of great artists who participate. It's not a competition, just a place to learn from other artists and have some fun.
I just posted a new Jam and welcome anyone to go check it out and join in! You can find it here: [link]
If the images don't show up, you may need to register.
