I say stick with the style of the last two, but make them have color. It's great having those spectacular c4ds blend right into the render. Just black and white is boring, needs vibrant color. I'll say the thing about the first I don't like is that even though there's a light source, everything is lit up. Places need to be darker, like to the right of him. And the Bottom right corner should have a c4d behind everything. So it's not blank.
