Little update )
I've deleted the post with the Ganesha anatomy, after all this is your entry page, and your work should be seen here.
If I were you I would add some more mass to latissimus dorsi muscle that belong to upper group of arm muscles. It could refine silhouette and make it more masculine.
Cheers
