Checkpoints should be at least 64u thick so players cannot accidentally miss them by going too fast (also for consistency).
You probably have to move them to take up a room instead of a doorway to make this work.
CP3 can easily just take up the whole platform, for example.
I thing having the end zone going up to the ceiling is preferred here.
In-game entities:
Map should probably have an env_cascade_light. Use the new tool in entity tools for this, export to Lumper, run the job and remember to save.
Zones: all ok
Bumping on glyph's review about moving spawnpoints.
There's a v2 of this map with some boring skips prevented, should be used instead IMO
