Hey there cringeyigns,
Unfortunately, I will be REJECTING this map submission.
Theme: For your theme, unfortunately, I'm going to classify the theme that you chose as unoriginal. We've already got so many different types of Christmas/snowy themed parkour maps and yours isn't much different. As well as the fact that we've got a champion map with the same theme.
Build: Sadly for your build, there isn't really any sort of definite structure/build in your theme to really bring it to life sadly. Your map is basically just floating blocks and a snow/ice wall.
Parkour: For your parkour, firstly your blocks are all over the place, floating and not connected to each other which makes it look rough and messy, not attractive to the eye. Your parkour is not varied and feels quite repetitive at times. I suggest that you add more interesting types of blocks/jumps to make your map more interesting, such as anvil jumps, chest/enchantment table jumps, etc.
Thanks for submitting this map! If you have any questions, feel free to message me here on the forums, in-game, or on Discord.
