Hmm those robotic race-cars don't really seem to fit in with the era? Reference to some game/movie/other I don't know about maybe? Also, the lines between the difference pieces could blend together better I think, at first it's almost like it's the same image, as if it's a curtain of light waving in on a dark world, with the underworld war ravaging below. Drawing's look good, but they could be patched together a bit better I think. Keep it going!
