Mario, I like the composition, the way you builded up the song. and then the sax comes in...!
A nice Jazzy Blues I heard.

A little remark I want to make: the volume level is the same throughout the song.
I rather would like some 'expression'(changing in volumes of some instruments). That way your song gains on dynamics. At least, that's what I think.

Nice day,
Hans
