Hi there,
I do like the theme of this map, but I feel as though you have not executed it well. First of all, the build of your igloo is not the best, because it looks a little more like a tent. Moreover, you have not put a lot of detail nor effort into this map, and the blocks you have used for your parkour do not match the theme. However, although I have not tested it, I do like the parkour, as I believe it has a lot of variety (based on the pictures you have provided), and it looks really fun. I am going to give you a -0, but if you change the igloo and/or add a bit more detail I will definitely change my rating.
Good luck,
Allie
