I like your colors, but a more subdued gold tone-on-tone might work better so doesn't stand out as much. Just my preference, but I'd like to see what happens when you move your lights into center and frame with your darks, or inter-place them more. Also could try to turn inner triangles so points face in on 4 blocks, or as suggested all in same direction to see how that flows. I'm sure it will be nice when all done.
