I have entered into one such competition with Ironmonger (Mark) and here is my work in progress:
My basic concept for my Deldar vehicles stems from the awesome concept art for Tron Legacy. I wanted the piece to be asymmetrical, but with balance to make sure it felt weighted on each side. This is just the high light process for the glow, having yet to wash the model. I have painted the base for the hull, and the body, hull being Valejo Charred Brown and Black (70/30) and the hull is straight black. I plan on layering up moderate brown high lights on the hull with a badab black wash for finish. The body and rider will bright, intense gray high lights, and some areas will receive a glossy finish.
