As Ben points out you need to liven it up with some sort of noise or mottling effect..keep it on seperate layers as an over print plus the transparent blue grey lay to tint it....not so it looks blue but so it doensn't look grey.....in other words you only really notice it when you turn the layer off
As with all effect, keep them subtle, add several but don't over do it strength wise on any layer, build the effect up over several.
For example you could have several noise or mottle layers with different size effects rather than try to do it all in one
A good effect is one that has an effect without looking like the effect has been added as such...if you follow.
As Ben says......experiment and as I mentioned keep every effect on a seperate layer and do whatever you think until you're happy.
As it stands it is beaching too much. A silver will look very much duller on the PSD's. My SIlver City Superfreighter for example looks very dull.
Any overall colour is hard to give life too but silver or any kind of mid grey is about the hardest.
Having said all this...when you do hit the spot you well really feel a sense of pride.
It is certainly worth the effort
