I like the two-toned Mach One with Black and the bullet holes are in line with my thoughts. I'd prefer a silhouette of the F-4 Phantom and in black as well. You used black aircraft in your other renditions. The letter O in One could have a mach meter (speedometer for aircraft) with the speed at 1.0 - A mach meter starts at .1 and goes to 2.5 - I have flown at mach 2.4 which is 2.4 times the speed of sound. The mach meter could have tick marks areound the dial and the needle at 1 to indicate mach one and the speed of sound. That would be cool.
Looks good. Can you try and have a camoflauge pattern on the letters? Also, I'd really like an F-4 sihlouette. Move the word "Mach" up and lower the word "One" and use the latest upload of what I am looking for in a red/white/blue contrail. Just suggestions on what I think I'd like to see now.
