I don't think the game should start changing things to round, because they have always been square and that is the style, the feel you get from Minecraft.

I disagree with a round sun and moon unless there are plans for the phases of the moon to actually affect something(potion making, special enchantments, dunno what else) because then it would be OK since a square moon with phases would most likely look worse than having circles.

Otherwise, I say no and have voted.....
