First of all, FYI, it loaded in about a second and a half for me. Maybe the other guy experience some network congestion when loading your site?
I'm not really sure how to critique your site. Artistically speaking, it looks good to me. From a business perspective though, if you want people to contact you to design stuff for them, it's gonna cost you potential customers. Everyone is different, but a lot of people have a certain "untrustworthy" response to very dark websites. As a graphic designer, that probably won't be a huge problem as it's rather common to see graphic design sites that break that rule.
Like I said before, in short, I like it, but I'm not sure about the overall "darkness" of the site. Hope that helps.
