I can't put my finger on it, but the white space and the gray boxes make it kind of bland. There's no punch or anything visually to draw me in. It looks unfinished in the sense that there's really no visual elements.
The bottom gray rectangle almost looks like the page got cut off and I need to scroll down more to see the rest.
In the about section, you use both "we" and "I". sounds a bit weird when reading it. Also, for your contact page you should implement a contact form. a good one to use thats pretty simple is formtoemail. its a good PHP contact form that I've used in a few sites I've built for people.
