I agree with Geo, biggest-head + original colors.

Do you mean grey jacket and no extra colour on trousers, rather than blue-ish tinge jacket and lighter trousers?

Yep. I think the lighter trousers had too much contrast, and I think the grey jacket rather than the blue-ish jacket makes the sprite more interesting to look at. I think that one on the right in what you posted there is the one to run with.
