The composition, mood and arrangement are great! You need a better frequency balance in your mix I really think (too much medium). It sounds muffled, muddy and a little bit hard on the ears. All instruments share the same space in the spectrum. you should add a little volume in hi mid and a lot more in treble on each medium and hi playing instrument, more bass on the bass instruments. You have to decide where each instrument (in orchestra context I would say group of instruments (hi strings, low strings, Hi brass, low brass…) will peak and attenuate all other instruments at that place (if nessacery). It’s very important that the kick drum and the basses not peak at the same space in the spectrum. I hope I help a bit.
