Heyo! Super glad to see a new map submitted! Here are my thoughts;
THEME:
The theme seems to be unique, as we don't have any igloo themed maps.
BUILD:
The build is made very well! The block variation is good and there is a fair amount of detail put in. Some of the outside parkour can blend in when looking from spawn, which can be positive for the builds look but a negative for those who think there's less parkour. Personally, I would've built the end into the igloo's roof, but the way you've done it is still appealing.
PARKOUR:
The parkour is pretty easy, but there are too many jumps. Either make some jumps harder and make the map a medium or get rid of some unnecessary jumps. Otherwise, the parkour is enjoyable and fits the difficulty well.
Overall, I think that this map is well made and clearly has had effort put into it. I wish you the best of luck!
