1. wrong key. megalovania is in D
2. red 1 is so jittery wtf
3. red 2 is offkey
4. red 4 is offkey
5. the part that isnt the chorus starts too early
6. yellow 1 and 2 are kind of unnecessary, yellow 2 is off key
7. unless its a remix you're doing, some of the things don't belong with others like putting the chorus with the verse
8. the changes between blue 6 and 7 forget me up, the sound change is so drastic
9. blue 7 is offkey
10. blue 8 is offkey
good job
