The Bad news:
Every once in a while, in the photos I catch a faint gleam of too-thicvk paint. I see ity cause I do it ALL THE TIME myself, and I'll be honest that I am sick of the Smokescreen mold, but I don't like it the way I used to. Far as the vehicle mode, the only complaint I see is that I personally think you used too much yellow on the hood flame, but one of the Classics Hot Rods did the same thing too. (And I didn't like it there, either.
)Were it me (and I had your talents) I woulda gone with a U or a V shape with the flames, high on the side (top) of the hood but not as far up in the middle. Maybe only as tall as the Autobot insignea
The good news:
For a Prime Hot Rod, the mold is the best choice. You've pretty well nailed the Robot mode perfectly, with enough detail in black and in gold to visibile but not gaudy. And usung the Mechtech gun (modified, I see) for his Animated crossbow gun, is genius.
