That is very pretty. I do prefer your previous picture though, but mainly for the colours. I think this one would benefit from a bit more darkness around the edges, so the viewer's eye would be pulled stronger towards the light. I find myself looking up the tree trunk, up the branches (I'm guessing around the higher third, if going by the rule of thirds), then looking at said branches and thinking they feel a bit flat. I understand that they're not the centerpiece here, but I find it very easy to stare into them, looking over the glowing creature. So I think that a "frame" of dark shadows would help keep the interest on the animal. As well as darker shadows on the roses would make them feel closer. Of course, that's just my opinion and following this advice could easily break the style, but I thought I'd share. At the end of the day, of course, you're a more experienced artist than I am and the image is rather pleasing to the eye as it is.
No, I definitely appreciate the comments, and agree in most cases. I really have to watch my screen more often than I do, as I have the 'Flux' ap, which changes the colours drastically, as was which happened in this case.
