Hello loveminecraft1,
I regret to inform you that your map is being rejected.
The theme is original, as we don't have any diamond and/or emerald specific maps; this, however, is not the best choice for a theme.
There is no main build, which is a crucial issue. Every map needs to have a main build; something that your parkour can build off of.
The parkour is quite repetitive throughout with emerald/diamond blocks, so try to incorporate different jump styles throughout your entire map! This may include; heads, water, lava, cactus, vines, and many more different types of jumps depending on your theme! You do not specify a difficulty, but I'd say this is between an easy-medium map.
Thank you for submitting this map, I would love to see more submissions from you!
Have a nice day,
Kristina
