Definitively feels "tropical". I like how relaxing the melodic lines feel. Sounds nice for relax in a resort. ;) I would recommend you to take a look to Latin rhythms, montunos, bossa nova, clave, etc. This kind of music is very rich with rhythms, and these rhythms are something very important. For your piece, I think you should slow down your percussion and give them the same relaxing mood the other instruments have.
Also the percussion is panned too much to the left side. If the soundfont does not let you to centre it or pan each percussion instrument individually, you can try and export the percussion and make a mono wav format for each single instrument of your percussion. If it sounds good and not extra noise added in the wav file, then you can import them back to your sequencer for pan them freely (and add other effects too).
