Ori and the Will of the Wisps - Howl (Piano Arrangement)

It's a boss fight! A short one, but still a boss fight.
It's also easily the most physically demanding video I've made so far (although not necessarily the most difficult due to its length). It's filled with octave tremolos and jumps - while I can reach up to a 10th (with the right setup), it's still tiring to maintain anything beyond a 6th/7th for extended periods of time, especially if my hands tense up - it took a lot of practice to mitigate that.
A few things I'd like to improve:
At measure 5 (0:13), that right hand chord needs to be a stronger and held for much longer. I'm not sure how though - I feel like I used as much force as possible without sacrificing the bass, which I think is necessary to maintaining the flow of the piece. The alternative is making the bass less prominent, but that's easier said than done.
I'm not sure how to go about the section at measure 6 (0:16). It needs to be tense throughout, but at the same time build up to the next section starting at 0:33. The last two measures are do that to some extent (measure 11 switches to an octave left hand and in measure 12 the right hand becomes a trill), but the first four rely entirely on dynamics, which I don't do a great job of.
Halfway through measure 13 (0:38) the left hand is delayed a bit too long.

Really cool Arrangement, sad that no one is arranging, howl, it is beautiful. And yeah like you said, it could have been improved, but its hard to arrange something so vocal with crescendo's and stuff. Still really cool arranged
