I'm sorry, and I know this probably isn't my place to say, but kokew00t's post really annoys me...
Anyway, Dog, I think this piece lacks a certain clarity and leans towards the messy side of things.
I really don't know what that blob underneath the dog's tail is, but I'm assuming it's a rock for this crit:
When working with only 2 shades, you really need to work harder to define shapes.
That rock is a bit of a dithery mess, but if you broke up the speckle regions with solid black or white chunks (in places), you could define the shapes of the rock through a lightsource.
Edit: Well apparently it's a turd, in which case I think my crit still stands... but whatever.
