Remove the portfolio site from the portfolio dude - everyone knows you must have designed your own portfolio site Maybe you should have more details about the services you offer on the main page, and then the portfolio in detail on another page.
The design is okay, I think everything generally looks "too big". Also, ever tried going to deviantart for photoshop brushes? I've noticed you've been using standard ones
Make the screen shoots smaller , maybe also some link to the real sites ? if people want to see how it look ... etc
