It's hard to separate the actual musical content in this piece from the various pyrotechnics and scalar runs. Upon first hearing the piece, the orchestration makes it sound unfocused and diffuse thematically. I know that in the score it says that you have sopranos, altos, tenors and basses, but in the performance I don't hear any voices. Instead I hear strings but no Violin I, II, Viola, Cello or Bass parts. Because of this, I'm not sure what your intent is regarding the instrumentation. Also, if you intend to write for voices you're spreading them real thin by splitting them 4 ways in certain places. Usually strings will be the bottom-most section in an orchestral score but it looks like you have percussion at the very bottom.
I feel like you filled your piece up with too many 16th (and in general - fast) notes . Maybe you feel like you have to do that to give the piece a forward rhythmic drive and excitement, but I think you might be putting too much emphasis on effect and not enough on the actual musical content of the piece. Your ideas follow one another without really seeming connected to each other and the piece doesn't end but just stops. Usually you can tell a piece of music is well structured when the listener can tell that the end is coming up soon because the musical ideas will direct the listeners expectations but that doesn't happen here.
Although, on the positive side you definitely seem to have talent and a cornucopia of musical ideas. I think bringing a sense of thematic unity and variety to your ideas would make them more coherent. Thanks for sharing!
