I agree with the majority of The_Traveler's comments, but I also like your shot. It wasn't presented as a professional portrait that was created in a professional studio and I wouldn't judge it by those standards. Despite several faults, it also has several strong points. A fill flash would have helped to save detail in the girl's eyes.
As a candid and an amature character portrait, I think it flies very well. It has an interresting subject. I like the composition. I like the pose. The expressions of both the cat and the girl creates a relationship within the comp. I'm particularly fond of the axis of the eyes being on the diagonal and located near one of the ROT's intersections. I like how the detail in the supporting cat element has subdued is subdued so as not to compete too strongly with the main subject. I like the bokeh DOF.
In general terms, I think your image was a very good effort.
