I use photoshop 7 at work and CS at home. CS has got a few new things but the two work pretty much the same. I dont think its really worth it, but it may have some new features you might be interested in.
Its seems abit dark in the center, I had to look kinda hard to make out the film strip.
Also the drop shadow on the text at the top looks a bit much.
Overall The design looks good.
