For the palace set, the key point was to place one of the two decorations in the middle of the four, so all four touch the one. Then you only need three decos total as in contrast to four. I don't need happiness, so you just drew the design that I was thinking about like a day before

The elephant set was a design I did not think about. The fountain with the attack/defense is too big and thus, I did not care about it. Arranging the rest of the buildings so that FP, medals, gold, and supplies can be earned is great. I don't think I can get all items since I am still trying to get all towers for the four palace set up. At least six are needed and I have currently five.
