Above are examples of the style I'm going for of a standard and basic airplane.
After folding several airplanes I began mapping out the process to give me an idea on how to model it.
Modelling
And here's my airplane model I made, with the help of this tutorial. I simply started out with a flat polygon plane, then added several edges for the folded creases and began moving the vertices to fold the airplane into place.
Texturing
I finished with texturing the model with a white crumpled paper texture. I quite like the end result, however I've noticed that it can be quite difficult to see the folded areas of the airplane unless there is a definite contrast between the light and shadow.
Animation Tests
In my first test I focused on the speed and acceleration. I thought the plane should increase it's speed as it's swooping down but then slow down slightly as it dips back up a little. I was testing for a more natural look with the plane flying down in a simple direction.
Where as in this test, I started playing around with the movement of the plane. It flies in an unrealistic way as if it's got a mind of it's own. I also tried rotating the plane's body according to it's movements, which I think works well giving it a more organic feel, rather than just staying still and folloing the motion path.
