shaved doors/boot, lowered and removed the rear indicator/reflector from the side of the car near the bumper, desaturated the interior of the car and around the outside of the side windows. (you have desaturated all of the visible area behind the windows, however you should have not desaturated the area visible in the distance through the front window, and you havent desaturated the interior areas visible through the rear window)
try show wheels australia, they have a decent gallery on their site -
showwheelsaustraliaon these cars i think you cant go past the 'victory' or 'vista' style rims
with your colour maybe your contrast is up too high, just play around with the "Brightness-Contrast' and with the "Hue-Saturation" until you get the best effect, it takes a little of fiddling to get it right
you do need to remove the curtain from the rear window and get privacy tint
nice job so far keep going looking forward to seeing more updates
