Yes it will definitely look better with a lower rear end. The fork will be more raked as well. I imagine once the extension and the chain stays flow in the same direction like a continuous line everything will tie together. Basically you have to tilt it until you find the angle you find most pleasing to your eye.
It will be also the easiest way to avoid eventual chain line issues.
If you want to drop it even more remember that the lower the drop the lower go the first (original) set of seat stays - and since they go narrower at the top this means the chain will have to pass them at an area where they are narrower so they might interfere with the chainline.
