I don't know if you did it purposefully or not, but in the beginning, your kick drum is off beat by quite a bit. you might want to fix that.

Usually when i start building a track, I start with a drum loop. Create a vibe that feels right to you, with bass, snare and hi hat to start. After that incorporate sounds that fit that tempo (or change the tempo to fit the loops you are using). I feel like the notes in this are a bit off too - maybe it's just the order but it sounds strange.

Just take a second to restart. You'll get it.

You need to make sure all the beats and samples are playing at the same tempo and arranged in a way that makes sense. I don't know what Mixcraft is. I use Garageband. The best way to understand sequence is to listen to a song that may have inspired this one and then take notes on why that sounds the way that it does. What is happening in the song that makes it so good to your ears and then try to replicate that in your song. I think that will help you understand what to do. I'm not saying to copy I'm saying to learn from that and really dig in to understand how the music works and all the subtle things that really go into it. We are all trying to do that. Doesn't matter what level.

Possibly start over and work on the beat first. It is definitely off tempo. You have a faster horn over a slower RnB drum loop. you need to sync up the tempo before you add any more melody to it.

this would benefit from a hi hat so the listener knows where the beat is. It sounds out of sequence. usually there is some sort of beat indicator running throughout a song so that the listener doesn't have to find the beat. it doesn't have to be that way if you are looking for a specific sound. It doesn't even have to be a hi hat it can be whatever you choose. the kick sounds great. all the samples are fighting each other. I'm only trying to be helpful and not tearing the track apart. I think these comments may help you get to where you want to go. keep it up.
