Hello Elephant3,
Unfortunately I will be Rejecting this map.
The theme isn't very original as there are already many maps with the theme of minecraft blocks/items. The build is quite plain and simple, and not very attractive.
The parkour isn't bad, it could probably use some more variety though.
Almost all of the parkour is floating, in the future try to implement the parkour into the build more. When parkour is floating it makes the map overall look more messy, so try to avoid doing this.
Thanks for submitting your map! I hope to see more maps from you in the future.
