In terms of silhouette it's similar to previous sketch, I wanted to keep a similar silhouette but tweak it more, instead of being horizontal on the shoulder, it's a bit rotated towards the back.

This allow me to incorporate some of the other ideas I like from the first round of sketches.
-the arm holding the demon arm, and somewhat add like a carrying/dragging touch to it.
-the severed end is somewhat like an opened mouth and horn
this way the head can attack as well, also an attack from the demon arm would be more powerful as it swing from the back.

Thanks a tonne for everyone's feedback and also ~lychi's awesome crits~!

I'm somewhat ready to start the final beauty shot for the char, i'll add the last round of detail touches and design when I start the final design~
