Very nice overall, just a few tips.
On your DigitalFX page, your buttons have those dodgy-assed white dots around them. You can get around this by making those dots translucent and saving as a PNG24 with transparency.
Also, in the abstract theme, the webite name looks a little, well, out of place. I'd suggest going for a cleaner font, something similar to a Tahoma, and swapping the bevel-and-emboss effect, perhaps for a strobe & textured transparency?
Aside from that - will you be selling designs?
