Hard Work

My first day shooting with my new 400D, getting use to depth of field, aperture ect. We had an assignment in college to take a picture of someone that conveys "work" I had a shoot with a friend set up, but it fell through so ive not finished the project yet.
But I was messing around with taking shots and this came out. and the first thing I thought was that it would make a good "work" picture.
