Still haven't moved that arm, I see... I really like how the image is rendered, but I can't get over that arm, it looks like it's sprouting mid-collar bone, right next to the neck.
I haven't mastered anatomy or anything like that, so this probablly wrong too... but at least it looks more correct. Also, the image comes off as very stiff, I tried moving the other arm a bit and that did help, but now the 90 degree angle of the other arm is even more obvious (possibly because the anatomy doesn't distract as much)
