Nice work making what you did! I see berlin orchestra mentioned in comments, it's not bad but unfortunately good sounding orchestras are something you probably have to pay for (I used the free berlin and BBC orchestras in my entry). To get them to sound right you need to be able to adjust mics and attack of notes and all the things that are locked in payed versions.
I liked the compositions, I think I would have put the opening melody on something else, maybe and oboe that is then supported by bassoon later on, it's a bit odd hearring the horn playing really high staccato. Incredibly hard to play! Alot more idiomatic on reeds or just pizzicato strings. It would play the legato theme well i think. The melody didn't really fit the chords at the end in my opinion. The melody outlining the Eb major chord sounds a little odd over the F major chord in the progression, i think one of them should change.
Everything else was really cool, nice one! Maybe just some mixing on winter to get the reeds and strings to gell a little more with the ambience (if you had more time I'm sure). Would love to hear more stuff resembling the last track!
