there's a lot of stuff going on here but i don't feel like the electronic elements sit very nicely over the orchestral parts at all - it's like there are two different tracks of very different quality playing on top of one another. the kick drums get completely lost under everything, the drum sounds are all really thin and play really samey rhythms except for the little trap-ish section towards the start. the eurobeat style synths are cool in isolation but feel very messy on top of the strings.
the orchestral parts are really good imo, very lush mix of strings and choirs. the celesta sits really nicely on top of the piano in those little refrains, these are by far the best sounding parts of the track imo. the mixing is a little dense and stereo-centered, it'd be a great idea to pan out your string sections and choirs to fill out the stereo field - you can use this to give the instruments more separation and make things sound "bigger" without making them too loud.
while i understand that you've put a lot of time and effort into doing a note-perfect transcription of the original, as a listening experience it offers nothing that the original doesn't already. it would've been really cool to hear you double down on the orchestral aspects, which is definitely where your strengths lie. keep it up!
