Hey silvermisst! I just had a look at your map and have a couple things to say.
The theme unfortunately is already taken by bighero6, in the future search around for a theme that no one has taken yet.
The build is okay, unlike bighero6 you made it 3 dimensional, so great job on that! A major issue I have with the build is that Baymax is a very rounded character, and your build is mostly square. Also the vast majority of the build is snow, in the future try to add some other blocks to add more texture and shading.
The parkour was okay as well, in comparison to your last submission, there was definitely more variation to the parkour. While it was long for a medium map, I found the difficulty to be fitting for the parkour. My recommendation for future submissions would be to have less floating parkour again (mostly inside baymax) and to add more variation into each individual checkpoint, not just having each checkpoint have a different type of parkour!
I hope to see more progress from you as a builder and parkour maker. Thank you for the submission and good luck!
