This is absolutely laden with atmosphere.
Kicking off with Havet Og Marah, I love the lead that intermittently comes in and out from the intro; makes me envision something bobbing on the surface of the water, occasionally dipping below but bouncing right back up and treading further. The orchestral bed below is arranged really well and feels glued together properly. Nothing out of place or glaringly identifiable - all layered nice and tight so that it creates a sea of ambience. As the piece progresses, it gets a little busier but still remains evocative.
Rolig Sjøendans feels a little more like a typical orchestrated arrangement. A definitive swing to it with some nice airy melodies swinging in the spaces between. If the last track had tightly packed layers, this has slightly looser ones and it feels more appropriate - I think this one in particular shows off your individual orchestration chops a little more.
Ending with Det Skremmer Meg and the tone change here is noticeable, but wholly welcome. Much more menacing, progressive and larger than life. Think this is a great one to finish on, and it does a great job of showing some versatility.
Great work!
