I like the smooth, jazzy beats and saxophone. The mix is a little quiet, but otherwise well-balanced and clear. The guitar at :22 doesn’t quite come through well, though - it almost sounds like there’s a bit of delay on the sample that’s making it sound like it’s tripping over the beat a bit. That said, my biggest concern is probably the lack of structuring. You have a couple of rough transitions, notably 1:05, and otherwise the arrangement feels a bit stale. Some more solos, a bridge, or a change in the harmonic pattern would all be welcome here. That said, the mood, sound design, production, and rhythmic content are all quite enjoyable here. Keep at it, Vioyoyo! :)

loving the fast samba feel and smooth instrumentation. the mix feels a little too chunky overall but i guess that's partly a limitation of the software instruments you're using. still think the bass can come down in volume once it kicks into gear properly. with the two accordions in unison, you should pan them a little differently and move the note triggers on one of them very slightly to avoid that weird phasing sound when they play open 5ths together. it definitely feels a little unfinished and underdeveloped as a composition, but i do like the progression and build it has currently. would be nice to hear a more complete version of this through some higher quality, multi-sampled instruments. make more!
