i do not like the city scape/ ninja combo, especially since the two colors conflict so much. i'd say either change the colors of the ninja, to a more subtle color....or change the city scape to anything but black. also, the ninja's a bubbly looking, while the cityscape is rigid and percise. it looks like to images and two ideas just slapped together.
