I'm starting my mix!

[tonixd]

Hi! I'm new here and I'm at my second year on a sound engineering career at a university here in my country (Argentina).
Next period I will course "Digital Mixing" and I'm practicing (Also I make my own music).
I just started a few hours ago and this is only a portion of the song, the first part. I will be uploading more than this obviously but I wanted to know opinions and advice from this great comunity.
So, please tell me what about my start!

Thanks in advance!
