For energy it's quite slow. You do good by adding more instruments and rhythms as the track progresses but you wait too long it ultimately feels dull. Speed up the transitions, shorten the track. It has a nice beat and rhythm. I liked it.
I personally enjoy slow and dull songs. :P But I will put it into consideration of speeding up the transitions and shortening this long track. Thank you for liking it anyways. :)
Please contact me if you would like to use this in a project. We can discuss the details.
