I apologize, I somehow missed seeing your post earlier. I was looking at your Challenger, and you might want to try "Bare Metal Foil" for your chrome trim on the windows. It's a thin foil with an adhesive on it that you can cut and trim on the window frames. I'd also paint the inside of the wheel wells black to simulate the undercoating.
The orange paint looks great on her, what did you use?
I also like your trim work on the grill area.
The problem with the hood may be that the hood is warped. Removing material won't help, but you might be able to bend it back to where it should be. I usually leave them be on my builds.
Another neat trick you can do is take a photo of your license plate on your 1:1 vehicle and reduce it to fit the plate holder on the rear bumper. It takes a little bit of practice to get it the right size, but the results are worth it.
Thanks for sharing your builds!
