Nice manip, i love the colours you used to make it seem warmer and the cats eyes look stunning, not to mention the blurred out background really draws the attention to the cat. Though a few things are bugging me. I don't know if its the photo you used or the way you edited it but the cats head seems almost dettached from its body, like its just been cut out and stuck back on a completly random photo. But like i said, this may not be your fault i'm not sure, and if thats the case then theres nothign you can do about it i guess but blurring the cats body highlighted this and made it seem even more fake, which, while i think softaning the edges was an ok idea to make it seem more feral it may have been better if you'd of left it how it was and sharpend them insted.
Apart from that its only really the cats whiskers that seem kinda off aswell. Im not sure why, just to me they seem odd looking but still. One to their own.

But overall this is a very good manip and i like the theme/style you were going for, and i think it is effetive even though you may have been able to do it a little better. But yeh, still, good work 8D !
