Unfortunately, I must inform you that your map has been REJECTED.
Theme: As we don't have any Duolingo-themed maps, I can safely say that this is an originally themed submission. Good job on coming up with something new!
Build: Personally, I really like the build. I don't think that there is much to be changed at all as you did a really good job on bringing this green owl to life on Minecraft. If anything, I'd try to minimize the PK surrounding it as it makes look a tiny bit messy but that's nothing big. Great work!
Parkour: The parkour is the reason why I've rejected your map, but I hope you can re-submit it soon after revising it. Honestly, I think the parkour was a little repetitive. By this, I mean that the parkour was comprised of a lot of the same and I would really like you to experiment a little more so that your good looking map is also enjoyable to do. If you could address this then we'll be golden!
I hope you take these criticisms into consideration when submitting this or other maps in the future!
