Great composition! Love the melancholy vibe. You're getting (what I'm assuming is) some preamp hiss that builds in certain spots. The accompaniment sits nicely for the most part, but you may not want the rhythm strings to be as loud/panned-left as they are (and maybe slightly decrease the attack). It will help them blend and sound more realistic.
Keep it up dude! Definitely worth a scout. :)
Please contact me if you would like to use this in a project. We can discuss the details.
