I really understand the open design, and you are trying to show off your work more than anything, but it really isn't that high quality.

the dark green on dark gray is kind of gross, I don't like it, when I first clicked I had trouble identifying the projects from eachother, they need to have titles and be identified and more spaced. also get a new logo. try a new font on your text layout.

basically I would keep the basic way the content is lain out but change everything else.
