I know this is a bit harsh but I have to be honest so, please forgive me. I'm not exactly sure what you're trying to do. I'm hearing 3 different styles with a slow-mellow as a start leading to an orchestra of sadness in the middle, ending with a rock/jam beat.
On the bright side, the beat was consistent.
By all means, I'm no music expert but I do recommend that you play off the theme. Just the idea of Lavender Town in Kanto with them having the Pokemon Tower filled with Ghost-type Pokemon and the Funeral Hall. I would like to have something along the lines music dealing with sadness and death if at all possible and then maybe stick with a particular style of music whether it'd be Classical, Electronica, or Rock.
