Don't you dare!

This picture is stunning! I love the dark lighting, the glow in the two cats' eyes, the expressions and their positions in the frame, it all looks very powerful!

There isn't much you can improve on in this picture, but perhaps a few things!

The details on the cats are awesome, great job on the fur and the shading, but the background is a little lack luster. I HATE doing backgrounds and I always half-ass them myself, but they are at times an essential part of the picture! Especially with a picture like this that is meant to look like a screen shot, a more detailed background should be in place. The dirt and the grass don't have much of a texture, add some layers on top of that for the blades of grass and the rough gritty look of dirt. The trees look pretty good, aside from the lack of roots which could be put in for more detail.

All in all, awesome job on this, I really like it!
