Looking good Gabe. Nice finish and weathering. I see two fixable issues with it though.
The first is the rear lights. Only the upper left oval should be red. The lower left slit and two slits on the right (upper and lower) should be black. They are part of the blackout drive system. It should look like below.
The second is the tracks. They are too loose. It looks like you used the one-piece vinyl ones. If so, I suggest removing them and taking out a link or two, then splice them back together with sewing thread or staples, reattach them, and then rotate the splice up under the skirts to hide it.
Great moel overall. Keep up the good work and keep posting it.
