Yeh, I'm with packer, that model is stolen. There is no way in hell you can have a player model that looks like that, and a vehicle which looks the way the speeder does. It just doesn't match. Plus, the player model would be even easier to model then the speeder.
And JD, the blockland minifig may be alot more simple then the droid, but it's a WELL MADE model and probably uses half the polys the droid does, because it's mostly comprised of one shape, not a forgetload of primitives. Your droid however, looks like you put it together with your eyes closed. Overlaping stuff all over the place, and attempts to add detail which just look like mis-placed boxes.
