Great job! I love the colors and your knitting looks great!
I love sock knitting.....it is the perfect project to work on in the eves while watching TV with DH and it is compact enough that I can stick it in my purse for knitting while waiting for the school bus or the kids at swim team practice, soccer practice, band etc.
One piece of advice, I always cast on for the mate as soon as I cast off the first sock, otherwise I am tempted to move on to another project, but if I get it started (the trickiest part for me) than I will get the pair completed reasonably quickly. I have a few single socks floating around here waiting for me to make its mate.
