Too Much Brown?

Working away on the Canadian beaver. Slow going even tho I want it to look simple, it still needs a bit of shading to give it some shape. Its a lot of brown but unless I make the beaver um pink or blue, not much I can do about that since they are just plain brown animals.

Todays sketch is a plastic palette knife, I have metal ones but no idea where they are. Should show up sooner rather than later since the room is slowly getting sorted out.
