Hmmm. Are the arms supposed to be going slightly back behind the spine as they swing outward? I was trying to view his arms as the Z-axis for the page and it didn't quite come out straight in my mind. I was curious if you were going for a slightly more intricate detail than I could see. :)
It was more of just a straight up T-pose, the reference I used for this is from here: http://ahrum-stock.deviantart.com/art/basics-25-29877170
To be honest I'm still fairly wobbly when it comes to perspective and foreshortening so I'm afraid there are no intricacies here, at least not deliberate!;; Thank you very much for your comments, I really appreciate the feedback!
