I've been modeling for a little over 2 years now, I use solely Blender for modeling and Paint.net for textures. Feel free to post comments/crits on any of my work, however, the further back the pics are, the older they're going to be.
This is based on the assault rifle concept for "frontlines: fuel of war" found here:
I had been out of practice modeling for a while and used this as both an opportunity to make a fictional weapon from a concept and get back into the swing of things for a current project. I modeled this completely off of the concept and never looked at the real model until I was finished.
This is a render of the (quite disappointing) final product for the game: Poeghostal.com
