Split screen with slight color correction

Going back to editing the shot, I have resolved to use the colour corrector tool in order to get rid of the cut line in the shot. Using this tool, I adjusted the reds and greens in the top shot. My reason for this being the door. The door is where the cut line can be seen and the reflections/colour of the door could affect this dramatically.

I only adjusted the colours slightly as I didn't want a green/red tint in other parts of the shot, but I wanted to adjust it enough not just to get rid of the line, but to add a slight warmth to the shot. I believe this was a successful move because it appears to have improved the effect a lot more than expected.
