Nice piece! I like how it's attention grabbing by having contrasting moments in terms of energy and different textures, there are a lot of good stuff going on. I think my main concern regarding the composition is that while there are a lot of good things there might be a bit too much new and less development. It's for sure possible to make the first roughly 40 seconds into a 3-minute piece alone. As it is now it feels a bit "improvisish". There are some parts where the music goes off and creates energy which is really nice and contrasting it with the slower/softer parts helps create a nice drama. However, I wish that there would be a part where you'd let the music go free. For example, at around 1:07, this part is really beautiful and I wish this part would be set free. As of now, it gets cut off almost interuptet which is not always a bad thing but maybe build up the tension again and then let the music go free. A very effective way to create a longer coherent piece is to tease the climax by starting it and interrupting it. Maybe set the music free at 1:48 and then end up in a bombastic last climax was my first thought. In that case, planning out when to let the music be free is a good way to stay coherent, get a red thread throughout the piece, and build a nice drama.
For the programming/mix/producing I think playing around a bit more with velocity/pedaling/staccato vs legato could add a lot of diversity. Don't read into my comment too much since it's just my current thoughts.
Overall a great job in creating a piece that is engaging to listen to and I love your approach to a more dramatic piece!
