Thank you for the compliments *beams* but i can't take all of the credit. Most of my Star Wars models are based on Lucas Arts creations such as R2 and the various ships.
My Main Occupation is spent as an Engineering Drafter, mostly aircraft equipment.
As far as LOD and COL... Is LOD, Level Of Detail? And I am not sure what COL is in reference to. I am a self taught modeler with no formal training at all other than a 2D drafting Degree, so some of the modeling terms may be outside my current knowledge.
Also, let me try to render a better example of R2. The sample I linked to was just a quick render and doesn't show the finer details like his tool sets and such. And the ship prototype is a very basic shape that I am still slowly adding more detail to. Please keep in mind that any textures I use in my models are pictures and texures which I have downloaded from other creators. I don't have any good art applications for creating 2D textures yet.
