LSPD Livery Pack (Trenton Police Inspired) 1.0.0

This is my first attempt at doing any American-style vehicles, normally I'd be working on British Police, and at the moment I am working on a British lore-friendly pack which is proving to be more difficult than expected.
In the meantime, this is a small project I've been working on for a couple of days. I've tried to make these liveries reminiscent of the Trenton Police liveries seen in this video: https://www.youtube.com/watch?v=_OLgtVG-0nc

For the moment, it only supports Captain14's amazing LSPD pack with ELS lighting, which you can download here:

I'd appreciate any feedback on how to improve this, as I say, I'm pretty new at doing liveries that aren't British, but it was fun to give it a go regardless.
Thanks,
