Well for starters, I don't like the font thats used for the titles of the posts, its to hmm hard and in your face. Almost like it would hurt if i touched it, try a softer font. I don't like that navy blue/black that the posts are in either it kind of clash's with the rest of the site colour scheme.
I think you should work on the web site header aswel, its abit to dark. Maybe thats to go with the site design, but I woudln't really remember the header image its to plain and theres not enough on it. Thus not remembering your site. If I was you I'd look around at some other sites, ones that are in the similar categorie as the site your trying to make, and get some ideas from what you see.
Good luck!
Regards.!
