@Rogue one of your scenes for 2018 MENCS Camaro is up on the TMS rendering system now. But one of the guys called it 2017 by mistake. LOL Also one your other scenes for 2018 it seems like the spoiler is not transparent, and needs a bit of TLC. Just check out the gallery (paints that have been rendered by folks) on the rendering site and you will see what I mean.
Edit: check out page 4, or if more renders go thru look for the one with the # 1 cessna paint, it has renders of all the different options.
