i love this, but i agree with what Fluent said. The Switch up is amazing but at the start it legit sounds like future bass, maybe adding a simple no hat no snare/clap drum loop could help a bit
The first part of the song before the drop doesn't really fit the drop imo. I think it's because most deep house doesn't really utilize the future bass vocal style and build
I think there needs to be something introduced earlier that facilitates that transition. As it is, it's two different ideas smashed together, and it needs something that helps them gel a little better. It's close, there's just some little something that needs to be added to help it move from one idea to the next. For what it's worth, the deep house section is really good.
