I like your written melodies. I would have wished that the whole composition opened up a little. Some layering reverb and panning would make this easy listening track have a little more life in it.
Overall though I really enjoyed it and you are really good at writing! You give each instrument its on peice to play and it's own spot. For a 4 minute song, it was very enjoyable! Good job!
Please contact me if you would like to use this in a project. We can discuss the details.
