I really like it! Agree with everyone else on the greatness of this piece..
As a photoshop geek I find the glowing dust particles annoying since it's a default brush
Anyway.. its not a big thing
However you could make 4 or 5 different ones in different sizes and it'll look much better
Excuse me while I try not to die from how good this looks. It looks wonderful... Wow... Keep up the work, it's fantastic. I seem to lack in vocab to use words, so if I wanted to use words to describe this, maybe you should find a thesaurus and look up, "wonderful", "supreme" and "spiffy"!
