this may sound wierd… but it works… go find a good porn sight, not one of those ones you have to pay for or the kind that drop a virus into your computer, but something reliable like, redtube. i know it may sound tacky, but you will get the male and female form completely nude in about every position you can think of, and there is just alot of opportunity to learn and study the body and what its doing. you can screen grab whatever you need as reference. just ctrl “print screen” at the top right on your keyboard.
or, i also really like to have netflix for the same exact reason. if i need muscles, i play rocky or conan… if i need a pretty face, sky’s the limit. costumes monsters gore fantasy… its all on netflix.
and or a really nice photo book. i use mens health and national geographic… that kind of thing. but it helps to have many different angles of view of a subject. so, thats why i prefer video reference.
if you ever have an idea to do a giant frog as a project. i would say, if you really want to turn out an amazing model, go buy a few books on frogs. same goes for anything. if your going to be spending that much time on a model, and we all know it takes forever, then its worth the price of solid reference.   for your female. its comming along nicely… may i suggest you pic a specific person to model the face off of. it will give you a much better result than if your winging it. find a girl that you think is really pretty and get her to let you take tons of pictures of her. then, use a super model to reference the body off of.
hope this helps.
