Not bad for a start.
but some points to consider:
1. A little too much white background. It's a little like home walls without paintings.
2. I personally don't like lots of text at the homepage. If I want to know in a glimpse what your site is about, and you want to attract my attention and make me interested quickly, big blocks of text won't do the work.
3. The "About" section usually is placed in a page of its own.
good luck!
