I like the idea of the map itself, there is of course some improvements, I will list them below;
- Add some lava parkour (extra ways to travel from island to island)
- Increase the amount of structures.
- Differentiate the blocks used for islands; Using the same blocks for all islands causes it to become bland.
- Texture the floors and Decorate the map with some creative terrain.
Other than that, the map is overall a great design, keep up the continuous hard work and continue to make maps and submit them in the future!
