For some reason, I think that this would work as some generic grunt soldier drone, almost like a Vehicon. Vehicle mode isn't bad, though the robot mode doesn't seem all that articulated (which means freedom of movement), though I'm not sure how far you intend to go with the model. Don't give up though, concept wise, I think that this is very good and could turn out well if you keep working with it. Oh yeah, forgot to ask what program you're doing this in.....so what are you using
Well Starcracker, you just nailed what I had in Mind, Cannon Fpdder indeed and later one make a Tritank general, ala Tankor. I´ve used Moray for windows for the modeling, and POV-Ray for the rendering. Thanks for your comments.
