It's definitely retro. Now all you need is an old purple car sitting in front of a purple sunset in the background. Or, if you changed the color on the stripe, you could put in a white background and it would look like one of those old A-team vans, put a picture of a surfer in, any number of things. It's a very versatile design.
P.S. if you get a chance, take a look at my gallery. Any comments, criticisms, advice, etc. would be greatly appreciated.
