Synth Latin
The thing that I'd say that this track really needs is some sharp horns in there, to give it a crisp contrast and really sharpen it up for some of the moves that the dancers can make to this piece. I'd consider throwing in a complete pause, where a singer might yell "HEY!" or something similar, to add to the way that this tune builds itself.
When you get into a rhythm and start progressing with the tune, I was going great until that winding down outro, that kind of went against the grain of the piece, as I felt it. If you had the two note ending, without the way that the tune seemed to run out of power.
Yes, it could stand to be a little longer and lyrics would give it more of a feel of something along the lines of "Copa Cabana", but you've done a good job.
