Is this map good?

Hey guys, I haven't made any maps leading up to this one and I wondering if its any good. This is my first map that I've ever made, so I want actual players to try it, because it seemed okay to me, but im not sure how good it is to other people. Its basically a map where you find super cool secret places hidden well, and if you find a really hidden place, you may find treasure! Also the challenge is to not break any blocks.
Its a world save file. not just images, so you have to put it in your saves folder and actually click on it in single player. If you are in creative mode, you can switch to adventure or survival mode.
the link for the world map is here:
