Hi, Adam! Good building and painting job, I also enjoyed the light weathered efect (even I prefer a heavy one). I built this kit a few years ago, a straightfoward kit, no adjustment, fit, gaps issues, etc. But I don't paint the windows to replicate bulletproof glass like you, nice touch.
This kit allows use of many aftermarkets, but, like you, I did not use any, and I just do some scrath to improve it.
With the correct observations made by Piotr, I also recommend that you check the sagged part of the tires. Some of then do not seem to be placed on the floor, looking weird.
