Don't know if it's just me, but for some reason the Scritch players in this jam have had some difficulties playing through the whole track whenever I've used it. Only got through the first 1:15. Might be a good idea to add the audio file to your submission for download.
But from what I can hear, I think the vibe as a whole is quite nice. The instrumentation works really well together, zi especially liked the walking bassline in this.
If I had to give some feedback (from what I can hear) I'd first say that the melodies seemed to fall on the downbeat almost everytime. And for this style of music, maybe consider emphasizing the melody on the upbeat occasionally. A little bit of syncopation could go a long way for this track.
I also felt like some of these instruments, especially the sax, felt noticeably MIDI in the way it sounds. Whenever this comes up I tend to experiment with the note velocity a bit to try and make it feel more natural. Plus this variation can also lead to some nice dynamic changes in the musical phrases it plays IMO.
Thanks for sharing what you made, keep up the good work :)
