Hello, I've looked trough your screenshots and I've visited the build in-game. Would like to state that this build is in Creative.
If I recall correctly, I can review builds as trial mod so here it is:
Beauty: 3/10 - I like how you shaped the hills under the island, but the actual island could use a bit work
Uniqueness: 3/10 - reminds me of an Easter egg, mazes are not exactly new but yours was interesting and the "mysterious men" aspect could be expanded a bit more and made more interesting
Execution: 3/10 - not sure if the box on top is a house, maybe turn it into one with more details and put the door there; actual maze inside was kind of fun but could use more details (also once you're inside the quartz area you can't get out unless you fly)
Scale: 2/10 - this build is on Creative server, it could be bigger and more elaborate
In total: 11
...which, unfortunately, is not enough for Apprentice rank.
You can re-apply in 7 days (with this or new build)
A suggestion: I'd make it way bigger, since it is in Creative and there are no limitation as to blocks you can use. You could do an egg kind of build or just build something very elaborate that is interesting and pretty to look at, really lots of things you could do to improve this before you apply again
