Number 3 and last in the line. This is the most realistic and true to.. well, myself. I like this one the most ^.^
I think this one is the best out of the three too - very nicely done - we had to do self protriats in art class a few years back and it's so hard!
whos the girl?
I think this one is the best also. It seems like you have a knack for likenesses. Don't rule out the first one either, it definately has a good style. Keep it up.
