I'm gonna go out on a limb here and say I could rock with the guitar/synth arp if it didn't sound so dry. Could probably also use some more elements before that drop. As is, the mix kinda feels empty.
I also notice you apply distortion to that synth later. Garage Band string and key instruments are just kinda universally terrible for this kind of music. By 2:07, I'm feeling the feel you probably wanted around 1:11.
Outro was not bad, but would have been way better if it didn't cut off abruptly. Not sure what happened there. I know in my DAW this will occasionally happen if you select a section and hit render. I'm not sure if maybe you wanted this to loop or not.
Regardless, this feels incomplete. I'd have liked to see more done with this minor chord progression rather than just two chords with the root a semitone apart. I can't think straight enough to analyze what exact chord each is but it essentially felt like the same 4 measures repeated, with no real variation. I get that this is house, but if you listen to most house, they will also have more instruments, textures, percussion, and sound effects coming in every 8 to 16 bars to keep things fresh. They also will use longer progressions and add more chord tones as they go on. You were starting to do this at 2:14 and I was hoping for the track to go on in that vein.
I recommend looking at some tutorials for the genres you want to produce, studying how they structure their elements, and try to apply some of their principles to your own work. May also want to check out some basic videos on music theory and voice leading. You're off to a good start, but there's always more to learn. :)
There are also free VSTs like SQ8L, Dexxed, and APBL (ample sound bass plugin) and AGML (I think) that can supplement or replace some of Garage Band's crummier synths and help improve your sound.
Thanks for coming out to NGUAC. Best of luck with your music. I look forward to seeing you grow!
