Very very nice, I'll start with my few complaints because they are rather trifling and more of personal preference than real critique. The perspective, while incredible and dynamic, does seem a little wonky and makes her right leg look veeerry long. Also, her ribs/abs area seems just a bit overly muscular, but like I said that's just a personal opinion and not critique.
I love the colors and shading, love the quality of the line art, it makes me feel like this was beautiful even just as a sketch. Your light source also looks really good, which is something that I seem to have a tough time with. I also, like others here, really like the pose and the perspective. She looks tough, sexy, spry, and she has lovely little tits. (Thanks for avoiding the "tried and true" huge boobs on an athletic character formula. While it can look nice, this is much more convincing and appealing.)
Anyway, it's excellent and do keep up the good work. :)
