Animal Acrylic Grisaille Painting

In my Concepts class we were doing acrylic paintings of an animal reference photo in the Grisaille painting style... doing a drawing, and then a value-study, and then glazing transparent color over top of the value.

This was my reference photo:

And then the drawing of the reference. The arm in front when drawn out didn't look correct so I was essentially forced to redraw the arm from a different reference photo.

We were given a color scheme, which mine was Complimentary colors, so I chose blue and orange for the final painting.
