You've crafted a very energetic and fun dance theme here, and while I don't really have anything negative to say about it, and it ultimately sounds very organic, I'm here to offer up constructive feedback regardless. The Adventurer demands it.
First off, I applaud the source of your inspiration, and have personally spent far too many hours listening to the hauntingly beautiful songs of Skyrim. I suppose it's a testament to the game's legacy that I still very much enjoy exploring, battling, shouting, and generally meandering across land and sea whenever the mood arises. You have done that experience great justice with this rousing folk song, and all that's really missing - to my mind - is a competent bard to sing of The Adventurer's praises!
The main melodies are lovingly crafted, and sound like they could be spilling from one of Skyrim's many alehouses. The violin strings sound a little extra slippery at times (too much rosin, perhaps), but I can certainly appreciate all those jaunty grace notes all the same. Your instrument choices are highly appropriate for the genre, and the overall mixing and mastering feel highly polished.
Key changes. Who doesn't love key changes? Once you hit the midpoint, they happen with relative frequency, and they seem to go up, up, up! However, I feel that the sheer number of key changes could have been supported even better by additional changes in tempo. As the notes rise in the scale, so too could the frenzied speed of the dance! Just a thought, mind you...but it seems like that sort of Riverdance-esque increase could really benefit the mood by ramping up towards the song's climax.
As much variety as there is here, I must admit that I hoped for a slightly more varied tale as the motif progressed. I sort of guessed where you would go with the notes, and you went there. But sometimes I hoped you'd go in a slightly different direction and change the narrative a bit. An alternate minor key here, or switching up to the major key there. Nonetheless, this isn't my tale to tell, it is yours. Chalk it up to artistic differences, I suppose!
On a final note, in regards to your ritardando before the applause, I personally found it too brief. In my mind, I heard a more pronounced slow-down in the tempo, over a greater portion of the end of the song, even before it arrived. In reality, it was quite a bit more abrupt than expected, and the tempo never quite felt as though it eased up enough before the applause. I feel like a more subtle ritardando could have begun in the previous section, becoming just a bit more pronounced before that final note.
All that said, I truly enjoyed the journey from its humble soundscape beginning, right straight through to the applause! No complaints, just ideas—respectfully, from one artist to another. Thank you very much for sharing this with us.
