No Inspiration

I'm not going to lie to you all--I've been pretty uninspired lately. It's almost as if I've temporarily forgotten how to draw. For instance, below is the latest sketch from my sketchbook.
Now, I'm probably being a little hard on myself, but I just don't think that this drawing has the same life that my previous work has. What do you think? Maybe I need to add a little color to this drawing--that may liven it up a bit. Or perhaps I'll add a grunge background. I'll try it.

Dang it, I forgot to add my signature! What if someone steals it?! Oh, well, I'm not doing it now.
