Looks very well defined.  Reminds me of some old box art to 16 bit games on the Amiga.  Can't think which ones exactly but it's got that feel to it.

Done. :3

Agreed that you should integrate the text with the background more; it doesn't gel as it is. That said, the background is cool!

 I agree, I would try darkening the lines, or at least use one of the dark colors in the pallet you used in the background

Text is hardly readable... 

The white lines are obscuring the background. Big time.

Maybe darken the lines a bit, or try simulating a bit of transparency?

 Don't know what the background is supposed to be but the white text/lines are ruining it.
