Ludwig, perspective help.

Is his head suppose to be turning like that when his body is to the side? I'm not sure what pose you have in mind but I'm just letting you know they are both at different angles. Most artists make that mistake alot.
His arm looks rather strange. I'd just you make "joints" first before making an arm. His elbow shouldn't be that farm ahead of the bicep. His head looks good but I hope you don't add that much detail around the mouth area, it looks strange. The hair on the right looks odd too. It should cover a little bit more of the skin by his eye like the other side. I hope this helps and good luck!
