Hi there,
here is my rook which I am very proud of. I think it looks pretty awesome. I decided to add more pinnacles on the top and added them by subdividing the edges on the top, aligning the new edges to be right-angled and extruding those new faces up. I think that gives a very nice look because the pinnacles are not from one corner of the rook to the other but between them.
What do you all think?
