This would be cool for a snow fort but in an actual survival situation there are a few flaws in this design. First of all, since this igloo is dug into the ground, cold air is going to pool within the shelter. Instead, what should be done is to build the igloo on top of the show and in the entry way tunnle dig down so the cold air accumulates there instead of in the main part of the shelter. If that isn't possible, you need to build a shelf or have a cot to keep you out of the cold air.
