Awesome rod, Oran!
A very sleek and convincing design, the chrome stuff fits very very well here. My favorite combination is the first one. Concerning the front axle I think you did a much better job than me.
To get the whole thing even smoother - have you thought about these tires: rear
Another point: What about changing the color of some parts (maybe the hood or what is left of it) to get some contrast? I think this also might add to the appearance of the rod.
And a third point: The headlights are missing on purpose, I suppose. I feel the rod might look better with headlights, since IMHO it doesn't look like such
a mean machine. But that's only me.
Anyway, great job, very well done! (I think I will try something with that 6 x 5 x 2 base, too - as a black part it actually looks very well.)
Keep it up!
