Developing clean line work
I chose this thumbnail because it fits the brief. I imagine that the flat underside is able to enter the atmosphere safely, the wings indicate that this is a highly manoeuvrable craft, while its chunky body alludes to a cargo-based role. I feel the ship is at once small enough to lead on to some bigger ships later in the game, while big enough to feature offensive weaponry. I take the design into a new document and start sketching out the line work. Doing this on a perspective grid avoids problems later on. I throw in a figure to give the 3D modellers an idea of scale.
