Hmm, nice minimal intro. I would add a little reverb to the hat to add to the atmosphere. When you have the 808 kick hit mulitple times shorten change the release so that the bass is not overlapping and distorting. Ride is like 4 db too loud, and the hard panning to the right is disorienting. Generally turn up drums and turn down melodies. I like the idea and the melodies, mainly what you need to work on is mixing. Solid beginning!

I like your song's melody lines and sounds, It starts a little slow but takes off nicely.
As a suggestion (because of the Mexican mythology title) add some more "tom-esque" percussion. This piece needs a little more strength on the rhythm.
