I need some help with a building

Hi, I want to build a massive watchtower, and I already asked AI for an idea. It gave me an image (see attached), and it perfectly shows what I want to build.
The problem is that I’m not very good at building in Minecraft, and I’m nowhere near the level needed to recreate something like this myself. So I was wondering if anyone wants to help with building this tower.
