If you put a grey square on a yellow background, you will percieve it as slightly blue because of the unnatural contrast, that same grey can be perciebed yellow if you put it on a blue background. Maybe you wish to go for a more grey tone than blue tone at that right version? It all seems fine to me BUT I would personally still prefer to see some shading in the hair or a definition of what is cloth and what is hair to see the shape more clearly.
