Crack the Skye

So, I was playing around with some modelling tutorials to get used to the different modifiers and working with geometry in different ways, and I combined what i was learning together to make something geometric.  It started out as 1 little piece and next thing i know.. "hm, what if i duplicate this, rotate this, duplicate this and move this here" etc...  Viola, a little space project in about 30 minutes.

Definitely took me a whole minute to figure out how to go into the modifier stacks once i'd done all the work to start deleting out sections here and there (a small hint, create copies instead of instances).
