yeah thats suitably "double dragonesque" if memory serves me.
works better now with the alternating light/dark areas on the sprite. adds more definition against the background i'm sure.
are u underlaying attributes on this? or are u doing just mono to preserve your sprite's colour?
the shading on the darker side of the shaped car bonnet (hood) could probably stand being sharp black rather than dither. keep the dither on the lighter side and try going black on the opposite. it is shiny metal afterall.
