Reply to Frist song from scratch using Ableton Live/Launchpad. Comments appreciated!

Hi everyone, this is the first song I've ever made with the Novation Launchpad, using Ableton Live. All the loops included in this track are made by myself from scratch. Would appreciate your comments and tips in order to improve.
The song is called Brief Flight. Thanks, and hope you enjoy it!
Here is the video on youtube:
