first of all, I really liked what you did there musically. Your songs had a cool flow and gave a very gentle and pleasant feeling of lightness.
However mix wise I‘m a bit torn. The piano and some other instruments feel like they‘ve been low cut to aggressively so the feel hollowed out and missing much info below 500hz. This can be heard specifically in the first song. Second are some higher instrument, like also the Piano, flute and synth stabs that seem to be very strong in the 2Khz gange. This leads, specifically in the third song, to some shoutiness sound wise and gets overemphasized with multiple instruments that have the same effect.
Composition wise I really digged your songs, but sadly I do believe the mix doesn’t do it justice yet. Which doesn’t mean that it’s overly bad. Really would love to hear an improved version if this, gladly also with some feedback on Discord, if you want.
