Background help

[Olooriel]

I'm no expert on perspective, so no idea there, but I would tentatively say that the reason why the colour scheme isn't doing it for you is probably that the foreground and background are completely disconnected and don't appear to be part of the same environment, affected by the same lighting conditions. This kind of separation might work in a rather stylized picture, but the painting style of the figure is rather realistic, so we expect the cool lighting of the environment to affect it in a natural way too - skin would not look this red under these conditions. Or alternatively, cast a warm light on the objects in the background. The local colours can still be cool in the background and warm in the foreground, but the lighting has to tie your image together.
