The first passage has a jazzy feel. I play clarinet so I enjoyed it when the clarinet came in :) The second passage... seemed to hard cut too much for my taste. If the classical sound was what you're going for, then it's seems you got a more jazzy/contemporary sound.
As long as you've expressed what you wanted too with your music, then you've accomplished your goal and you need not the approval of others. As far as my opinion for the comments sections, I think this track was somber and perhaps could use some sort've smoother transition between sections or maybe a more shocking hard cut that doesn't sound like you switched radio stations, rather more like WHAM you just got hit with change boi! Usually a tutti fortissimo diminished or augmented chord or even an atonal section does just that.
Your composing skill is apparent, don't give up if you truly enjoy this endeavor. Keep sharing on NG, we'll all add in our two cents when we can and do appreciate the work you provide. Thanks for sharing rockossss :)
