The parkour is very nice, it fits the difficulty, it's fun, and it's varied. Good job!
The build isn't that bad in my opinion; I think the bun color should be changed, and it looks a bit flat, but it's easy to tell what it's meant to be. If you don't think the build is good enough, by the way, take as much time as you'd like to fix it! There's no rush.
The theme has been done before, unfortunately; there's already a map called Burgers.
+0, good luck!
Keep in mind, I am not an official map judge; take my review as that of a normal member of the community <3
