Hey, merci beaucoup !
That's exactly the kind of mood and picture I wanted to create, I'm glad it works for you.
I had very limited time to work during the jam. I decided to focus on the sound design and the mood rather than the composition itself. I have much less experience in it and I thought it was a good time to learn a thing or two. I agree there's some lack of momentum, it's something I would have worked out better with more time.
And...yes, I get your feeling at the end, I also feel it ends too soon. The track could clearly benefit from another part and a bit more variety. Maybe I'll continue working on it when I got more time.
