Thanks for the comments guys. He is self taught, with the exception of work study, and internships. I like the third one the best myself, but want him to explore a couple of color options. He had a little bit of a rebuttle for you guys:

"I have spent a total of about 20 minutes on all the designs, so any criticism of the designs are welcome- they should know that creating a logo is a process if they are all full time designers like me. However, I must say that criticism of my talent is a little premature and uncalled for. I don't normally design logos as they are not my forte."

Just thought that I should let him comment back on your comments. Thanks again.
