Two things about the colors and design...
Sometimes we as designers DONT get as much creative freedom because there are clients who request, demand and sometimes outright ignore what we as professionals say about complimentary colors, the rules of three and whitespace..
That being said... I actually liked the website. I mean, it is what it is. Its Yoga and to me, the theme seemed appropriate, colors seemed appropriate...for me, it looked Yoga-ish to me...colors, design, balance...etc.
I think he nailed it, I think the clients probably loved it... While its not something he'd probably do for every client, it was appropriate for who it was for...yoga people...a breed unto themselves...
