Great Site. The dark theme isn't bad at all. However, a few adjustments i'd suggest:
1, images. especially your past projects should be represented with (at least) thumbnails
2, your graphics, should be shown directly on your site BEFORE someone downloads them
3, embedded email form would be useful
on the flipside: i like the clarity of your site, your terms and cond's are well done as well. Not quite conventional, but still very neat.
