Aah, I remember this photo, was a pretty awesome panther jaguar. I like the warm colours you've got going! The way the spots are added flattens the foreshortening a lot though. Even with reference it pays to know construction
Do it. I've never been one too adventurous with colour but even I can recognize the opportunity here. Whether it was intentional or not I love the stark contrast in the hues. Folioage would only accentuate it.
