Wow @Nazariy,
For me this is very beautiful!
I like your introduction using bare B first and only invite E major later. This certainly reminds me the opening of Beethoven's Ninth.
Very beautiful tremolo in b.24! Except is the C# in first violin in b.25 not in tremolo or just typo? I like how you keep the B in the melody at the end of the 1st subject to match with the beginning.
Your transition is great as well by modulating to e minor, Eb major then B major. I love your motivic usage in the 2nd subject and the climax is bulit with great preparation. The orchestration is very good here.
The opening of the development by quoting the two motives from both subjects. Your modulation to Eb minor and introduction of triplets is fascinating and it for sure reminds of Brahms. You then modulation to Gb major and F# minor which is good, but for me having the Eb minor reappear in E minor as retranstion is not too wise a choice since E minor is already featured in the opening of the development. This reminds me the development of the Eroica Symphony, but the keys aren't used there before their appearance.
Nevertheless the horn reintroduction of the main theme in recapitulation is great. The move to minor subdominant in the coda is great since it's a usual scheme and it helps build up the ending climax once more by having a cozier key. Great ending as well!
Congrats for writing this Nazariy! Really looking forward to your later movements!
