Galaxy project, Island #3 (part 3)

Took ages, but finally done with the 3rd island, the one that caused me most troubles with all the command blocks and spawners not working how I wanted them to work, I posted the picture of the island in the previous post, so not to repeat myself, and not to spoil it's whole inside, I'm going to give a screenshot of the entrance to the main temple inside of it. It's completed in 99% actually, since I still have a couple books to write, but that shouldn't cause much problems and should be done by todays evening, so I can start working with the 4th island. In the meantime, the secret easter egg is growing bigger and bigger...
