+ liked the vibe and the whole structure of this song, brings out that happy feeling, like mario?
+ bass lookin' kinda sick there
- maybe tone down the reeverb there? sounds a bit muddy at parts
- the sax or whatever is playing is wayyy too high. maybe put it an octave down
= just my suggestion, but maybe add some ghost notes to make it more funkier? ooo also try messing with the slides. (also known as the pitch bends) you'll get a lot of good vibes when you use it right ;)
