@Glory, after seeing the posted pictures from jamvib, i think your blue needs to get a little more turquoise in there, your blue is.. to blue; the real car has a more offblue to it, yours looks just like pure midblue
When I do gold, I add some 'noise' to it to make it a little 'flecky' if you know what I mean. Actually the colour is good, but it needs a little niose, maybe only 5%. (I'm talking photoshop here)
I already though about that and probably will do it when I'm happy with everything else. As far as I know I have to convert a shape to a normal layer to add noise and I don't want to do that till I'm happy with the rest.
whenever i do something like that, i just copy the layer, do whatever i want to do to it, and then i can change the percentage of how transparent is from there giving me more to adjust and see what i like better so.. just a suggestion
