Paint and stripes??

I think you should do a combination of 5 and 6 having the nose piece and the dual stripes but the dual stripes across the hood and flowing down the sides. Somethings says lift the stripes up some and either make some diagonal breaks near the rear or come up in the center and across the trunk lid.
As for the color the black is classic but if you go with a red it may be too much contrast between the blue. Experiment with a darker blue on the front tapering off to a lighter blue toward the back sorta blending into the Petty Blue if not going across the trunk. Just keep lightning the blue as you progress toward the back and check the effect out. You can then ether pin stripe the top and bottom or blend it into the petty blue and then clear coat.
Let me know if you decide to look into this and send my a copy. Your drawings are good by the way.
One mans opinion!:-D
