I, too, would rearrange. Since you have already taken a pic of it, you can follow that if you want to come back to that design. I would bring the black over to the left bottom corner and then keep the blocks in the same order except change
every block so the main triangles are all going in the same direction. I would consider using the plain black as border #1 on the 3 sides but not where the plain black blocks are. Then alter the borders again, gray-white, and then black, but do
the opposite on the 4th side. Play with it, go out of the room, maybe leave it for a week, and then you will see a difference, and maybe one you are very pleased with.
