Well, here. I can give some brutal honesty. Initiate full improvement-based review.
-Biggest thing is that most of the instruments sound like they were recorded inside a small room. This is one piece which could really benefit from some reverb. The initial sound at about 10 seconds in doesn't, but the guitars certainly do. Use a bit of stereo widening and wider reverb.
-Strings are meh IMO. They're definitely better than a lot of strings I hear from early composers, but they can be improved.
-Horns can DEFINITELY use some improvement, though they're decent for a free library.
-A bit more clarity in the mids of the mix would go a long way.
-The birds seem a bit disconnected by the end.
-For some reason, the way the piece is organized just doesn't "click" for me. This is more a personal peeve, but the entire thing seems a bit underwhelming and 'weak'. The weakness is in part due to instruments being a bit overly thin, but otherwise the melodies seem like something you came up with on the spot rather than being something put together REALLY well. This seems to mainly be made up of chord progression, which is very difficult to do well.
Alright, brutal honesty mode over.
Seeing you've played music before, I can understand some of your skill with composition - it's good, too. Always refreshing to see a new artist who's paid attention to how music works. Your mixing is fantastic for just starting out. So is your use of many instruments. There are definitely things to touch up on, but this is still very good.
(also, keep going, say hello - I'll try to drop one of my more normally-formatted reviews on a track or two of yours, if you want)
