Hey Nick!
Welcome! Thank you for sharing some of your work for feedback. I agree with you - production is one of your weak areas right now. I would also try and learn more about arranging and actual composition techniques. When listening through several of your tracks, one thing to struck me was how static everything was in the overall feel and dynamics of your work. You have some cool ideas and I liked your music but there wasn't much evolution or dynamic changes from section to section. Part of this comes from better production chops but it can also come from becoming a better arranger and composer.
City of Synth was my favorite of the bunch! Keep studying and pushing!!
Thanks,
Nate
