I'm a bit of a sucker for jazz, and overall, I really enjoyed this song. I loved the melody, and the overall feel of the song.
My main criticism for this is that you seem to be stuck in a 'dramatic-epic song' mindset, and I always had the impression of latin music to be more upbeat and exciting as opposed to the darker, smoother sound found in this song. Maybe you had intended it that way, but it just seemed overly deviating from the genre.
Obviously, if it was intended this way, (i.e. another dramatic-epic song, just that this time it has Latin influences) then you can ignore the rest of this review because they are just my ideas of what a Latin song should sound like.
1) More brass. The fade is nice, but have it come in louder. More pizazz, and leave space between the notes so that when it is playing, it has more presence.
2) Slight change in the percussion.
A) Cymbals. Particularly the cymbal crash and roll. I love them. You love them. But get rid of them. They don't belong in a Latin chart. If you wish to keep them, then I suggest finding a different sample, one that has a slightly rougher sound and does not last as long (Drum set-like cymbal, not a concert band type)
B) Congas. Make them louder, and tone down the (Snare Drum?) used through the song
C) MOAR COWBELL!! ^_^
3) More variation in the sound+melody. While it works for a 1 minute song, if you ever plan on making it longer, it needs some variation
Anyway, thats my 2 cents on a Latin chart. I don't mind your dramatic-epic, but if you ever consider a second attempt, I would prefer it to have a more traditional Latin feel.
