Actually the balance is almost perfect. In my opinion. ;=; While the right side has a lighter tone/richer saturation, the left side is dark and low key. But there's a lot of action on both sides, so the far left seems to me a bit misplaced. Hmm, aside from text, I think maybe you could leave the middle dark, and perhaps add some lighting to the left. Maybe an orange saturation. Otherwise, it's great right now, nothing much to change. :P
