Looks awesome. Just be aware that if the sprite is the same size as the animations you posted, you might want to reduce it to at least 80-85%; use other vehicles for comparison.
It looks very nice, it just needs some highlights on the surface, at the moment the lighting appears too flat.
Is there any chance I could get the model and textures, I can add it to Fallout 2. The model will need to be converted to an OBJECT file. If it's not too much, could you make a boot for it, so when the player goes to the boot for their goodies it will open and close like a locker door.
