I don't know what you should add but I got a tip. Add the attachment in Jpeg format next time cos photoshop takes ages to open! What is your sig about?
You need to work on the red background. It's boring, plain and it contrasts greatly with the images. If you use brushing to create a grungy effect, or "Filter>>Render>>Clouds" and mess around with some filters, it will look a lot better.
i would put some semi tranparent grey wavy line going in a diagonal direction if i was you im not sure if you'll get what you mean as it hard to explain, well i hope you get some inspiration soon m8. Dave
