All my samples were taken from my packs. If you need inspiration for poses, emotions or clothes, you can easily download them all
Profile pictures don't have strict rules. An
example of profile pic with revealing clothes. We don't care much about pose, angle or how much body parts we show, they could be any as long as the picture is non nude and pretty. Moreover, some pictures in packs belong to both profile and rest, an
example. The character is relaxed enough for rest, but is not sleeping or something, so it's suitable for profile too. I'm telling it to show that profile pics have quite wide frames. But of course most pictures are like
this, when the character is simply standing or doing something minor.
Girlmeets pics are basically profile pics that suit cases when you meet the character somewhere, or anywhere in the case of neutral background. An
example with almost neutral background. Character is usually much closer to the camera, thus quite often we don't see legs or even lower body because of it. She cannot sit/lie, only standing pics. And she looks in the camera. An
example of beach-only girlmeets picture with another camera angle.
Thus, most girlmeets pics can be used for profile too. But only some profile pics can be used for girlmeets.
Here is archive with many examples of actions. I built it automatically with the help of file masks, so there could be a few clearly wrong images.
As for your pack, you could try to work with emotions. Stuff like shy or ecstatic very often implies blushing, so it might require another texture for faces, I suppose?
