This campaign is presuming I have no direct acquaintance with ancient pine forests imbued with a Celtic ambiance.
I wonder where this was shot, because those uniformly slim spindles seem more like a commercially / artificially planted young forestry that may or may not be located near any mystical lands.
I can see it being a Scots Pine plantation, as part of a rewilding project. All good, but hardly ancient woodland.
Reading the thread title, I was ready to be wowed. To me, it just looks like somebody went down the road during Halloween and sat down on the floor of a local forest, and then tried to sell me the idea that it was MYSTICAL.
