Hey Chris.
I agree with the other about the logo - I like it. It reminds me of the one for finch (getfinch dot com) He has a cool site - worth nicking some ideas from...
Your screen grabs look a bit pixelated - maybe up the jpg quality?
I like the background but I reckon it might look tighter if you put a gradient fill on it too, perhaps lighter to darker vertically? That might make it feel 'richer'?
I think you need to have a look at the content on the pages though - it all looks a bit empty? also, is it worth having the examples on every page like that? would it not be better to have a 'my work' section with them in and perhaps some smaller images as calls to action into that section?
Hope that helps.
