Xoon,
I like what you have. I added an idea in my last post. My idea was to combine the existing color and shapes to complement the existing fuselage. The curves combined with the lightning bolt were the theme followed. You can then add the yellow and blue to correspond with the fuselage (which is what it seems you were going for).

I have attached the design of the bottom of my current plane. The idea came from here on RCU however it was on a profile plane. I actually took a photo of an actual tiger and used the striping to create the cutting file. The orange color is Monokote pearl copper and the yellow is pearl also. The graphics were cut from commercial stock and are holding up well. I would change the eye color from blue if this is repeated on another plane. I like stripes of some sort to keep orientation during sequences. These are very visible on the 84" wing. If I get some actual photos of the plane they can be posted.
