Now... when I have the choice between that tiny photo and the big one at 
fig. 8 of http://www.fhsu.edu/biology/cbennett/science-v-fantasy-figs.html, 
you know what I'll choose...

What appears as a constriction and possible subdivision of the nasantorbital 
fenestra in your reconstruction seems to be a break in the left (but not the 
right) maxilla, judging from the big photo. (And the front part of the "left 
jugal" seems to be the left maxilla.) The fragments got somewhat pushed 
dorsocaudally, thus constricting the NAOF.

Your mistake with the dendrite would obviously not have happened if you had 
used a sufficiently big and detailed photo.
