Fabio,
Nice work - nice sounds.
As to the drums, they DO sound very good, but they are so far out in the mix, that they seem like the feature sound, and makes everything else but the vocal sound muffled. This, in effect makes them sound artificial because of the "sameness" and constant presence in the forefront.
I'm trying not to sound negative - I like the song, really! I sometimes have the same problem with my rhodes and piano sounds - I like to hear them so much that I often have them a little too loud as well.
Sometimes the tone of a "favorite" sound can overide the place in the mix, and that's what I hear in this tune. I'd try to back the drums off a little and brighten up the rest of the song. Maybe that's an American taste, I don't know. I really don't mean to offend - I like the tune, I do.
Keep up the good work, and thanx for giving us the oportunity to share the piece.
