0:34 was kind of abrupt ending to the piano. 0:45 was kind of the same but with the entrance with the instruments. I do agree with bloodisblue about the Mario coin effect and the overpowerment of the back beat too. I would suggest lowering the volume on it so it doesn't go over the melody. It's really good!
Very Nice Song
I really like this song. I think you got the parts of it very well and it came together very well. Only things I think you could do quite a bit better on would be 45-1:07. I just feel like you made that little back beat a little overpowering. Also the Mario Coin effect at 1:20 seems a little out of place (though that might just be me)
But overall very well done, I really like this song.
Please contact me if you would like to use this in a project. We can discuss the details.
