I'll leave the bulk of this for Nutritious because he's unequivocally better at orchestral production and arrangement than myself or halc. However, I'll throw you a few criticisms that I noticed this time around:
The start of the song is really abrupt, I wish it would start with a second of silence so the first brass note isn't cut off on the front end.
The main brass lead you used is, unfortunately, a pretty weak sample. There's a significant lack of articulation to it, which further exposes the thin-sounding sample. It ultimately feels like every note is being played exactly the same way. Once you get more of an ensemble brass section going and there's several instruments playing the lead melody, it's better.
The piano is still a sore spot, and I think part of the problem is in the delay effect you're using, which combined with the sample makes it sound doubly-unrealistic. More velocity tweaking (especially on the arpeggios) is definitely necessary here, and even then I still think you could benefit from a better sample.
There's instances with your leads (both piano and brass) where they'll start off at a perfectly acceptable volume, but then as more and more instruments are layered on, it ends up getting drowned out and the lead no longer cuts through the soundscape like it should. Watch your levels when you start introducing lots of instruments and make sure your proper sounds are making it through to the forefront.
The transition into a more electronic beat is nice (though there's some high-end percussion in the electronic beat that sound shrill and piercing, I personally wish there was more punch in your kick drum and less high-frequency percussive elements.) In general I liked the mixing of those two genres, I think you handled it nicely. This is a very solid arrangement and definitely does justice to the source.
A lot of these issues alone might not be enough to stop it from passing the panel, but I don't think it's above the bar once all the issues are compounded together :\ I really hope Nutritious chimes in his two cents on this, I think he could be a lot more specific and helpful than me and halc, but hopefully this sets you in the right direction when you go to make touchups. Best of luck!
