I drew this during a class when I was bored... its a Mitzubishi Zero coming out of the sun and shooting at a P-51D Mustang (WWII for those of you who don't know your planes)

The design and thought of it is good, and not too many people nowadays would think of drawing a picture with that kind of scenerio.

Though you really should work on the shading a tad.

Yeah the shading didn't come out that great. It's hard to draw clouds and all the lighting effects with just pencil.
