Critiques and Suggestions for a Half Life Dog model

So! Im fairly new to blender and cg in general, so don’t judge me too harshly. :wink:

Anyway, this is one of my first renders. Its the Dog Robot from Valve’s Half Life series. Please don’t suggest anything to do with materials, stick to modeling.

If you only want comments on modeling, why do you provide a render that is so dark it can hardly be made out? How about showing a wireframe at least?
