Hey xenobite,
Good news! I'll be putting your map into reviewing.
The theme is original, as we don't have any Raven-themed maps yet. What I like about your map is that it really tells a story. How you can see this in the build is such an unique concept! Even though the Raven is pretty small, the build looks great. There's a lot of detail to be seen, and I can clearly tell that a lot of effort went into it, great job!
My main concern is the parkour. It's quite repetitive and unvaried at some parts, as you mainly used normal blocks, ladders and some fences. Try to add some more variation in the parkour, with some different types of jumps! This will make your map more enjoyable to do. The parkour fits the hard difficulty in both length and difficulty, which is great.
Once you have improved the parkour or if you have any questions, please contact me via Discord (Uneasilly#8233). You can also start a conversation with me here on the forums, or simply comment on this thread!
Good luck and have a great day,
Sil
