Making this one sound better?

I'm a huge fan of Lo-Fi and slow relaxin, ambient music. I've started to create my own music and looking for a help with making it sound better. I'm usually using a main chords progression with bass line recored and then lay on top notes, impro and other effects. Everything is created on my Artutia MiniLab MK2 and FL studio 20. Thanks

Additional info:
. The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I'm hoping to find a good mixer that can work with my limited budget. I don't have a hard deadline for this. I'll need you to master it too if possible.
