I really like it. Like someone said above, the left arm looks a little strange, but I think it's the huge shoulder armor (a Blizzard thing!!) pulling it down a bit - and it doesn't matter too much.
I like the glint in her eyes, the way she looks at the viewer or the picture :)
Also quite cool that Blizzard featured it ^^
Anyways, thanks to Missrenew for linking this. :D I really appreciate it.
