I love it! I was thinking about participating in the contest, but I've noticed of it five days ago the finishing date...but my idea for the concept was near yours. A ship with solar panels, fast and dangerous. I would have named it with "Daedalus".
A pair of questions: - What sowftware have you used for? - It took much time to you to model the ship? (I don't know how to model in 3D, but I can wonder how much time it took to you to paint it digitally in photoshop or similar software.
