The aluminium looks great but I still think the blues are far too bold.
I put together a image with some blues as a guide for you.
The left most stripe is a representation of the color currently used - I used the eyedropper tool to grab the nose stripe color from your screenshots. RGB is 29/33/107. Hue/Saturation/Value is 237/73/42
The left center stripe takes the above color and desaturates it by a large measure. I also reduced the value by 2 to darken the color and keep it from looking too purple. RBB= 57/59/102. HSV= 237/44/40
The next 2 stripes are blues taken from other skins that I'm working on that I are a more true blue and not so purple looking.
Center Right: RGB= 58/75/102. HSV= 217/43/40 (This is my personal favorite of the bunch when viewed next to white)
Far Right: RGB= 48/70/112. HSV= 219/57/44
Finally, I included a US insignia to show the shade of Insignia Blue I used on my P-40's. RGB= 49/57/67. HSV= 213/27/26

You may also want to experiment with a similar treatment with your red colors.
