Hey Tirk2004,
Im not a map judge but I have some feedback for you which you may find useful.
When making a map make sure that the theme of the map is clearly defined and original. Sadly the theme of lava pools has already been used multiple times.
The build of the map has one main structure, but it could definitly use alot more detail, texture and enivronment.
The parkour has a good length and I like how you reused the slimes, but there are some things to consider when making parkour: Parkour cant be floating and needs block variety. This means that the parkour needs to be integrated in the build instead of floating in the air, Try to also use more different types of jumps and blocks like heads, pots, pistons, trapdoors etc...
I hope this is useful to you and good luck with your future builds! :)
