LOL fake. The sun isn't in the right place, and isn't nearly bright enough to reach that level of the cell cloud. It's far too dim. There would have to be two suns, one on both sides of the cloud. It would have to be raining/misting at that height (that part isn't far-fetched, I guess...), while the sun is shining (at that side of the cloud lol - remember, there is only one sun, and it looks like it's dusk). This is obviously fake. Not to mention the fact that "circle rainbow" looks like it's CGI generated anyway. LOL!!! However, regardless of the fact it's fake, it is beautiful. Quite a neat idea (ITB DIBC PIIMRN hehe)
