Cloth needs work
Overall it's very nice, I like the staging...there is a lot to improve in the clothing though, her shirt is right now probably the weakest part of the image, it does not deform naturally at all in the chest area
Other than that, the skin shader/texture could improve, the modeling could use fine adjustments on the body, expecially that leg
Did you do all the work here (modeling,texture,light,etc) or did you start from some premade base? And what software was used
?
