Cat in grey

I found a very cool cat picture on Deviantart. I had never draw so detailed pictures, it's my first try.
To make it clear, its not my cat and not my photoidea, i just made a drawn version of it. I used Photoshop and grafic tablet. ^w^
There is the original:  clovermirror.deviantart.com/ar…
I hope i linked it right.
