This may not be the most detailed thing I have ever seen, but if there is something that I have learned: Details DON'T make good pictures.

What makes this sculpture great is that it has the following:
-Solid construction
-Clever use of a light and glass to give it a glowing eye
-Nice texture
-Good design sense
In addition, I like what you did with its mouth, which gave it a strong expression and the drool was also nice.
