Firstly, I think the front panel actually suites the 'musclecar' theme, it reminds me of a big fat front or rear valance! maybe a vandle switch and a modders mesh grill from
mnpctech.com would just supply the finishing touches there!
As for the clearcoat issue, I'm not a biggy on spraying techniques etc but how long are you leaving between laying down another coat? maybe your putting another coat down to soon?
again Bill Owen AKA mnpctech-guy would have better advice on it!! or ask coel, he's pretty darn good when it comes to spraying etc!
Other than that, Good job!! the colours work well together and I think your photography skills aren't actually that bad!! what camera do you use at the mo btw?
If you want any advice on your photography then just gimme a shout! that is something I do know something about lol

+Rep for a great job so far!
