My eyes! >_<
But seriously, too much Xy stuff.
It looks cool and all, but aesthetically, I see it to look best as supplementary block, never the main focus, no matter what color.
(Plus the red lights don't help.)
If I may, I'd recommend maybe just make the wall outlines or corners as Xy blocks, and for the floor, maybe add some designs or large squares made of other blocks, some regular stone perhaps.
Lights may be best as white, considering the tone of blue the lights, they could be just as bad.
Yellow or Orange (or both) may work too.
But of course, this is just advise by my perspective (with some design basics) tho if you like it the way it is, then that's what matters most.
