Mine's almost done carbing now, but I've been having some anyway. I forgot salt and coriander in the boil, so boiled a cup or two of water for 5 minutes with those in it. This was added while racking to keg, right before the tequila tinctures were added.
My first impression was that it was too salty (I used pickling salt--was unaware I was out of pink Himalayan salt). Last night this didn't seem to be the case, though. Maybe that's because I was eating salty tortilla chips at the time. The tequila/agave and lime are there in the nose and on the finish, but are definitely subtle.

Well, I forgot to post for a few days, and it's pretty much carbed up and I've been drinking it a few days. I got good feedback from a lunch I brought a growler to. It no longer seems too salty as it did at the beginning.
To my taste, I'd like a little more agave and lime character. Perhaps this is because I found this recipe after having Founders' Mas Agave--an imperial gose that smacked you in the face with the intense flavors of Margarita. This seems a little more like a gose with a hint of that flavor. While I generally like my beer to taste like beer, with a hint of flavoring, this sort of beer is an exception for me. I've done Berliner Weiss with an obscene amount of citrus zest and loved it.
If/when I brew again, I'll probably try at least 6 lime's worth of zest. I'd also like to bump up the agave flavor, too, but not exactly sure how to accomplish that. I'll have to do some research on that front.
All that said, it is a great beer, and I'm definitely enjoying my keg of it! Thanks to OP and all the contributors in the thread. I don't want my personal tweaks to take away from a great beer.
