It looks pretty random/abstract but the image is slightly small to give a decent opinion on. It would be worth posting it here to get a wider opinion, but it lookd pretty good even as small as it is in the link.
If you can, try and scale it up. I'm not sure if it would be that easy though. It looks like a 3dsmax creation, that or photoshop. I enjoy it, but I'd like to see it with more girth. Your first work is definitely good for a first. :) Much better than mine was. Keep it up, and remember that size helps to get great feedback from the wonderful, experienced members here.
It looks a tad grainy but it's not bad. I like it. I agree that larger images are better for giving opinions on. That's probably why on this site you have to view a pic full size to vote.
