You should shorten it into a sig. Any way,The thing is good,The only thing that bothers me is the sparkly stuff,It just doesn't fit the picture,maybe thats just me. Other than that,Its a good pic.
For your first time with 3D text, it's pretty good. I like the color scheme that you used, it fits together pretty nicely. It'd make a nice wallpaper, that's for sure. The only think that's off for me is the matching lines on the right of the image, they seems to be just kinda . . . there, y'know? And the pretty sparkles might be a little too intense. Overall, well done.
I for one quite like the sparkles, I think it adds to the whole piece, the colours are beautiful. I also like how you've blurred the end of the text to give it more depth and all the lines give it a lot of detail. The only thing bad I could say about it is that it looks a bit plain but that isn't a huge problem, I really like this. Good job.
