Game of Thrones Fan art- Having trouble with the background

[katt]

Seeing as the white walker has a bluish tone to it, maybe you could make the background similarly bluish so he works in with the environment instead of contrasting against it. I wouldn't make the background warmer due to the setting and the feeling of coldness it should create. You can see in all of the scenes at The Wall that the editors have colour corrected them to be more blue to emphasise the feeling of cold.
