If I didn't know you were the creator of your 'Latest', I would actually say that you Sir are a noob. No offense. You could do so much more with that, it seems you just added effects to a stock and voilá. The idea may not be bad, but the ending piece seems... Unfinished.
Yeah, I was going to mention that it looks unfinished and I need to add something else to it, which I just cant put my finger on. But I thought I would just leave it at Cnc please, and see some real honest opinions on it.. i just can think of what to add to the background, i might experiment with some C4Ds.. but i dont want to to look cluttered. Thanks for the honesty though Gin.. i think i needed it to look at it fresh and have another swing at this one.
The render of cloud seems way to sharp or low res I might suggest looking for a higher quality render or stock.
use something like this and use overlay on it. it will look like something is popping out of the light! http://thewallpaperhunter.com/art/abstract/images/blue-C4D-l.jpg
