The BG is nice on the right I think, with a bit more expierience you'd know exactly how to execute certain things. Although I think the badge could be sorted out, seems too sharp for the rest of the sig.
The render looks okay but the cutting needs to be improved. Maybe add some render effects too, could give it more character.
The font isn't the best saying it nicely, seems somewhat 'childish' if you understand me.
www.dafont.com has some great fonts, download a bunch of them to help you.
Also on a little side touch, the 'bevel and emboss' on the overall sig doesn't look that great.
Overall its okay, especially for a "n00b" as your name would suggest. Keep going mate, well done.
