I had how to draw couples and how to draw...uhm, I forget the other one. but it had a lot of different stuff in it. I found both of them to be helpful at the time because they gave me pose ideas and such (especially how to draw couples, because drawing two people interacting is something I needed a lot of work on)

I think a good idea might be to check them out from a library or just browse through them at a book store and see if you find anything you think could help you out, then decide from there if you want to purchase them!

oh yeah, and something I've found helpful lately are various tutorials I see people post on deviantart. there are a lot of good ones to be found here, and they're free!
