Hello 46p,
I regret to inform you that your map is being rejected.
The theme is a bit unoriginal, as we already have a similar map to this with a very similar ukelele build (Aloha.) However, we don't have any specific "Ukelele" maps, so good job on that!
The build looks quite similar to 3D pixel art, which makes it look very simple and flat. I recommend giving your build more of a shape, as well as adding more details!
The parkour has a bit of variety throughout, and it is incorporated with the theme, so good job on that! It also does fit the medium difficulty quite nicely!
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
