Hi Aggie,
The lower half of her left leg seems a bit awkward to me, like it’s twisted to show the perfect side view. I took some screenshots of one of my characters in City of Heroes. Maybe these will help you get a more natural look.

I think her right thigh looks a little strange towards her hip. Maybe the contour lines are looking too much like parentheses.
I think your lighting is a bit vague, kinda reminds me of photos with cheap in-camera flash. IMO, it would be a good idea to establish your lighting clearly, and work that into both characters and the background as well. That would help ground them together in the same environment.
Good luck with your painting. Looking forward to seeing it progress.
