Well, to tell ye the truth, I am not too knowledgeable about space scenes, but my friend ~Entaryon is, and you can prod him if you would like another opinion.
So, in my unscientific opinion, I think this is quite lovely. The bright center is a really catching focal point, and the stars throughout it look like spilling glitter. It is defantely like an old picture of a nebula that the Hubble took some time ago... though I can't remember for the life of me what the nebula was called. *shrug* Ahh well, absolutely lovely work, and I hope your friend enjoyed it!
