The PsyD programs wont much care about your type of publication. It is interesting, but when we refer to "publications," we're talking about in peer-reviewed academic journals.
BUT that's neither here nor there, because PsyD's aren't generally research focused.
Considerations though:
GWU - You're stats are definitely competitive for GW; however, it is VERY expensive to attend and DC is one of the costliest cities in the US (rent for a one bedroom can get upwards of $1500-2500/month). It's apa match rate is also fairly low, with just 47% attaining an spa accredited internship. Not sure about in Mexico, but in several US states and the US military, that precludes licensure.
Yeshiva - Ferkauf requires 70th percentile scores, check on what your scores bring you to. They're also pricey (what PsyD isn't?), but their match rate is impressive (~92%); they definitely are, IMHO, one of the top 5 PsyDs.
Nova - You will get into nova, but if you heed any piece of advice anyone gives you throughout the pocess: DO NOT GO HERE. Their match rate is atrocious, their reputation is very negative, their cohort is very large, their faculty/staff/facilities are very unsupportive (just loo them up in some other forums), and their known for inflating the cost of their degrees by holding up people's dissertations (at least in the PhD). It is generally regarded as being just short of a diploma mill.
You're stats are fairly good, look up all the acred. programs and see where else might interest you. Take a peek at Denver, Baylor, Rutgers, and Loyola Maryland.

Good Luck!
