Okay, first of all that's a butt-ugly painting lol (it's mirrored, too, the intake is on the wrong side).
Second, as mentioned that painting depicts the 109E-4.
Third, there is already a yellow nose 109E-4. It's the default skin. There were no all-yellow 109G10 noses like that. By the time the G10 came around they were well well past that paint scheme. There is a superb 109F-4 skin available with a faded green paint scheme and a full yellow nose (I love it), but that's an F-4, not a G-10.
Fourth, you can't submit a skin for a plane that depicts the skin of another plane. If the planes are all but identical I think it would be allowed, but the E4 and G10 are as different as they can possibly be. HTC will never (repeat never) accept an E4 skin for the G10. The skin can be made, but you'd only be able to use it offline.
Fifth, there are plenty of interesting G10 skins out there. I personally like the one with brown spots on it.
