Looks like a good start, front needs more, but looks good. My suggestions would be:
1. Front grill, prob tractor, but maybe you can create something else.
2. Perhaps put the front bumper back on, just the lower flat steel.
3. Some minor fenders, think motorcycle/ trailer fenders.
4. Wood elements, like rails.
5. A unique gas tank. Something reused, like a keg, old drum, fabbed maybe, possibilities are endless, I even saw a rod at GG's with two old metal fire extinguishers as the gas tanks.
Good luck!
