Intro and drop don't match

This is my latest project, and i'm not happy with it. The intro doesn't match the drop, it never does in my tracks.
I know there's something wrong but i don't know what. Any help?

Does your intro and bass have the same root note?

All in C, just checked, That gritty bassline is in F though.
Always thought it was something with the notes, but in my drop, C & F do match.

Blend sounds that exist in the track with the intro, gives it a bit of continuity and makes the build of a track a whole.

I had this issue when I first started. The greatest tip I was given which helped massively is write 16bars of your track, these 16bars should include all the main parts of your tune all the drums, bass, lead sounds etc. EQ and process these once you've got these 16bars working duplicate them back to create your desired length intro and remove certain tracks this should instantly give you the bare bones of your intro and help you make decisions on sounds that will compliment it, pads, atmos etc.

Or take two of your tracks where the drop and intro don't match and swap them around
