The drums kicking in after just the solo piano in the intro was a bit of a surprise, but actually pretty cool mood switch.
Like others mentioned the UGH grunt felt a bit off, but i think to me it was mostly since it was very much in the forefront. Which made me think of how it would feel pushed a bit more to the background, with a wet reverb or just volume or a combination of both.
If you added another more contrasting in tone part to this, i think it would elevate the track even higher.
Just my subjective feels i got when listening, but still, good job!
