Pyramids, just pyramids

Certain have been building pyramids on a certain server, and not gonna lie has made me look back on some designs I've made in the past for a very large pyramid so I've decided to start building it again

there will be 3 pyramids the first being 29x29 blocks with a crypt underneath the structure, then a 57x57 pyramid with a very large aquaduct like structure below which connects to the last pyramid which will be 141x141 blocks with a city like structure on the inside
