Hello Tea_Sea,
I regret to inform you that your map is REJECTED.
The THEME of your map is original so good job on that! We do have a heart map but it takes on a different approach to this map.
The BUILD of your map is a problem. The build is very plain and small. Try enlarging the build to be able to add further detail. You can also change up the block texture to create a more attractive build. The shape is also very simple and not accurate to a hand, try making it more intricate using slabs, stairs, etc.
The PARKOUR of your build fits the difficulty and length for an easy map so good job on that! Your parkour is lacking variance, only things that are incorporated are regular jumps and ladders. To add more variance, try adding more jumps with unique blocks like pots, water, heads, vines, etc.
