The base tones sound like they use different tones
TIP
Put the lowest base notes 12 tones higher [Lowest base melody]
Then listen to it to hear what tone is wrong
Now it sounds like the base tones are in a fight ,no harmony
I think i would even keep it 12 notes higher on the lowest base
But if it plays the right notes than it could be ok
0;56 you let the low base play same tone
While high tone changes tones that sounds weird too
Good luck ;)

I will update a new version with a smoother bass progression, add some hats and fills too, thnks for the feedback.
