Once again, really nice. If I was made to look for major flaws really hard, I'd say that there is something about the cliffs that bothers me a bit, which imo don't mesh with the rest that well. They are less smooth, and also seem to share a different range of values than the rest of the picture, not beneficial to the overall consistency of the lighting (or perhaps its colors just don't work as well as the ones in the rest of the picture. I'm not sure if I'm fond of the green to purple). And maybe they're a bit too evenly lit as well? I don't know.
You could try spicing up the sky with a nice little gradient, becoming slightly brighter towards the horizon (just slightly if you intend to keep the cliffs as they are. At least one shade brighter though, than that hardly visible flame-esque aura surrounding robo. If you'd make the cliffs really dark, more silhouette-like, you could go quite a bit brighter.. if you feel like trying out stuff). You already have the colors for that in your palette.
