A few days after I made it my goal to finish my WIP's my pc stopped working.. so I took an unwanted break in that regard, which might have been a good thing in the end. It's been a month since then and I'm currently using my sisters laptop. I can now continue, need to start doing more studies.
If you're still looking for full body (female) reference material (and have $12/month) I recommend SuicideGirls.com. It's got an odd title, but it's simply a photo site dedicated to beautiful (and tattooed) modern women. They have an abundance of tasteful and interesting poses.
Barring that, I find TheChive.com and it's sister site, TheBerry.com, useful for female and male figure references respectively. Simply look for the entries dedicated to that sex. They're not nude, but they get awfully close.
Hope this helps in some way. Your work is looking very good and I am truly happy for your progress.
Take a gander (Sketchbook!!)! If you don't have one, a goose will do. <-- Lame Joke.
