It's Dan Dos Santos. He's brilliant--also did the iconic Dresden pic, plus some Sanderson covers, plus a ton of fantasy and UF. I always end up wanting to read the books he creates covers for. He is also the artist for the Mercy Thompson series (groan...great art, but seriously oversexed) and the Alpha&Omega books.
For some reason, it ended up in an All About Romance worst cover competition: http://www.covercafe.com/contest/2011/WO-res11.html
