I think it's likely that unless you're careful with your colour samples, this will turn out gray. I agree with the above sentiment that rendering on a similar-coloured background is deceptive with the kits, as seen on the boards. That said, if you're aiming for the very subdued, green-only-if-you-tell-me-its-green kinda look, it's pretty spot on.
Also agree that the enter key novelty is off and would suggest some sort of leaf design instead of japanese legends please. Otherwise, looks pretty good!
