ok, so here are some tips that might help, that I noticed when playing the map:
First of all, sometimes it can be a bit unclear where to go with the parkour. maybe adding more signs/blocks to stop going in the wrong direction would be good!
For instance, when you get up the water onto the honey bottle, my first instinct was to go straight on, not turn left. Maybe adding barrier blocks to stop them going the wrong way would be good
Second of all, while for the most park the parkour is good (especially for your fist map) what people want is flow, chainable parkour. this is done very well for he most part, but there are a few areas that aren't really the best.
Finally, a bit more variation with the parkour would make it a lot more enjoyable! you use a lot of jumps where there are heads in the way of the block, and while these are fun, there are a bit too many for my liking. maybe using things like ice, soul sand, fences and other different stuff would make it more fun to play
Overall, its a really well made map, and honestly doesnt need much change, and these are just some small things I noticed :)
