Hello unjolly! I will be putting your map in reviewing for the time being.
The theme is original and you can clearly tell that this is meant to be the Duolingo bird. The words at the top are a nice touch, as well.
The parkour is well-varied, fun and suitably difficult for a medium. However, it seems rather short (I counted 29 jumps). The final slime jump is also a bit hard because of how narrow the build is.
The build, as mentioned, is easily recognizable. However, as sillllllllllllll mentioned, it's rather flat, and almost like a 3D pixel art. You have plenty of space on the front and back to extend the bird to make it look more realistic, and you wouldn't need to move the parkour (other than the tail slime jump, which as previously mentioned, is a bit too hard. Moving the slime farther away will make the jump significantly easier).
If you can make the changes needed, I am willing to accept your map. Once you're ready for me to test the map again, feel free to message me in-game, on the forums, or on Discord (MCBYT#1337).
