Damn clean and beautiful. Colours seem perfectly balanced.
Only critique might be that you should be careful about getting the cat looking too grey. That said I know how hard black can be to paint, and your subtle grey midtones in the head in particular makes it look soft as you probably intended. I think it work fine on the tail though, but the head looks a little to grey to my taste. Or maybe it is the picture being slightly out of focus since the main model is obviously the girl. Great job.
