Did you play the piano? I don't know about Logic Pro X, but I do think the strings should be more realistic. The strings somewhat lowered the piano sound, a bit but not too much. I think applying reverb and a bit treble cut to the string might help! :) Overall, it is a nice composition but can be improved!
#Hey, I wonder if you do works like this, do you always do piano solo works? http://bit.ly/WYCBack is my works, feel free to visit :)
