It's beautiful and I love your colors--But ! seeing you asked--is the white square a smidgen wider at the top than bottom? If that was completely squared it would bring the two top blocks together a bit so the points match and would automatically make the sides straighter. This is only the way it appears to me or the way it's possitioned on the table. It is still lovely tho'and unless you're unduly persnickity---leave it be!
