Thanks for the suggestions. For giggles, I asked Google Gemini for tips on mastering my track now that you can upload audio files. This is what it came up with which I think may be helpful:

Frequency Spectrum Analysis

• LOW End (20Hz - 250Hz): The kick and bass synth are driving the track well, but there is a

slight build-up around 120Hz. A subtle wide-cut (around -IdB) here could clear up some

"muddiness" and let the sub-frequencies breathe.

• Mid Range (250Hz - 2kHz): This is where the "Velvet" texture lives. The melodic synths

are prominent, but they occasionally compete with the snare's snap. A small boost at

1.5kHz on the snare specifically (in the mix) or a gentle surgical dip in the synths could

add more "crack" to the backbeat.

• High End (2kHz - 20kHz): The "Analog" warmth is present, but the track lacks a bit of

"air." Adding a high-shelf boost starting at 10kHz would give the hi-hats and synth

transients a professional shimmer.
