Maybe it's just my monitor (wait no it isn't) but it seems the contrast/saturation is now upped way too high, so much it's starting to destroy the mysterious, calm atmosphere you had going earlier. Just turn it down a tiny tad bit, if you can. Not to say you can't leave it higher than it was before, just a bit.
Also I now realize the bunny's arms seem a bit odd; not quite sure what's wrong with them. As a next step you might want to pull of references for both the bunny and deer to fix this. The Creature's shoulders are a bit high but I suppose that's just the common odd-looking keyframes you find in animations.
