All right, cool holiday jazz and lofi theme you went for. Not purely on the mix first track bass is fine, the kick is a little muddy I would probably change the sound for something a little clearer. The trumpet sound can have more presence, the playing sounds a bit too MIDI, there is a couple free trumpet you can use for jazz one like Orchestral Tools.
Second track you can probably sidechain even more your kick with the rest of the track to create a bigger pumping effect for the lofi genre, I like the pads sounds its probably some chords that stays for too long mixed with the other instruments like the bells that mkes some small mud, you can probably cut some frequency to let the bells pass through.
Might seem a brutal comment but since its unranked I went all in to give my opinion, so don't be offended it seems alot but its some nice tracks overall :)
