In comparison to the other piece you posted here some time ago "Escape" this piece has much more recognizable themes that recur and are clearly in high relief. You pass the themes between different sections of the orchestra. Your form still lacks a direction though. The way to improve that is to give your themes clearly recognizable characteristics such as "Transitional Theme" or "Ending Coda" or "Expository Theme". Composers also like to write themes to deliberately contrast each other. How you express that through words is your own choice but I've heard descriptions such as "Masculine Theme" or "Feminine Theme" used to pinpoint the difference between them. One is more assertive, and prolific - the other is more lyrical, and song-like. The reason why I'm talking about this is because it still sounds like the music could just keep going and going without ever leading to a conclusion. Writing themes that contrast each other or that do different things or function differently within the overall form of your piece will help you to direct the listeners expectations and to arrive at a logical conclusion in your music.
But your music does in fact have the character you meant to portray "The Angel of Death". So good job with that. Thanks for sharing.
