that looks awesome!!
Just an idea, but try to bring more contrast into the picture. it might make it look better, or it might just completely fuck it up, but it's just an idea. lol (going off of JDMxDB8's post)
like... use the charts in photoshop to bring out more light and darken more area's. I'm not 100% sure how to use those features, but I use them to bring out things in pictures that I'm trying to put more emphasis on.
Please don't take any of my comment as saying your picture is bad. It's all constructive. I'm far less experienced in this then most of you guys are. I just got into the whole graphics thing.. lol
