Nice work as always. The logo looks better to me at full size than it did reduced to OOTP's 150x150 size (I run into that problem a lot).
Anyway, a couple of small suggestions, if you don't mind.
The star in "Tejanos" appears to have been rotated and then put on top of the text. It hasn't had the same perspective applied to it that the "Tejanos" text has had, so to me it looks somewhat odd. The star looks pasted on rather than being an integral element of the type.
The same problem exists with the "San Antonio." It's been rotated to the appropriate angle, but it has had no perspective applied to it like the "Tejanos" has. Again, it makes it look a bit odd to me.
I'm wondering what the logo would look like if these two elements were given the same perspective treatment as the "Tejanos" text.
That's about it. I find the overall colour contrast to be on the dark side, so maybe the red and blue in the flag being a bit more bright and vibrant would give the overall logo more contrast. But as always, that could be just me since my monitor is set fairly dark.
Congrats again on taking the gold medal.
