Not going to lie to you. This is quality. Everything from the gradual buildup to the sudden drops, everything is amazing. I, the critic, would like to thank you for uploading content that made me feel like I was in an adventure.
It made me think of something you'd hear in a classic RPG or performed by a philharmonic as an ending piece. It screams piano sonata, but at the same time brings forth strings and percussion, using synthetics that are close to actual instruments helps too!
Sorry if I go on, I'm not trying to be sycophantic here, but I love this style of music. Thank you again.
