Nice job, VERY good for a first sig, i agree with what everyone else is saying, you may just want to use the same elements you have and move them around, play around for a little while, and even if you come up with the same thing, youll nowwhat looks good for future reference. very good though 10/10 for first sig. alsoyou may try to blend your render a little better than just a circle type shape, take the eraser and a grunge brush to erase some of it maybe. just a thought. good job though.
