Keep going dude!
Beat 6/10......The piano felt too fast. The drums were simply boring and repetitive.
Length 10/10....Very good length.
Melody 8/10....Not very interesting after a while. 1:49 is pretty cool
Variations......8/10 Few variations. You need them, especially with this length.
Mood.......7/10 You had cool intro. At some places the volume flared up a bit too much. The outro needed something breath-taking and different.
Total 79/100 Very good! Keep working at it.
PS- Remember, you're being rated next to the best, so be proud. This is an awesome score. Practice makes beautiful. ; )
