I started with a few different sketches for the client to choose from, using a Sketchup model as the reference for the plane. I liked the first one, but it wasn't the best composition to include a character in. We decided on the second sketch. My biggest concern was that the composition was too much like the piece with the jet (Treize's commission).
I decided an early morning scene would help with that issue. The sky is just starting to lighten in the background, making the scene rather dark in the foreground.
I decided to redraw the plane at this point. I think it fits the perspective much better, and it's more interesting being larger and closer to the viewer.
