Beautifully eye-catching pattern! There have been very few puzzles that have sectioned off the grid into two (or more) separate pieces, and the best ones have a deliberate and clever reason for doing so. I liked the idea behind this one, THE TIES THAT BIND explaining that there are four types of "tie" that serve to sort of connect the two subsections. MAKE CONNECTIONS isn't that snazzy of an entry — most people say "network" — but it does the job to reinforce THE TIES THAT BIND.

Oof, the fill. Oof, I repeat. Let's study one corner and figure out what happened.
The SW stood out for me, with STORERS an awkward word taking up valuable real estate, along with RATA (hard to clue in any other way besides [Pro ___]), a prefix in DYS, ORI partial, and not just ESSO but a second gas brand, AMOCO — this one (mostly) bygone.
FAR CRY felt partialish, but I can give that a pass. ACCT NO is something I see on documents, so okay by me although not great.
As a constructor, you have to be brave to put YECH in your own puzzle.
Why so much, so concentrated? The CO of CORD does fix some things into place. The bigger issue is that the 6x4 space is already tough to fill on its own — I try to find ways of avoiding big spaces like this — and when you run a long themer through it AND fix two other letters into place, you're asking for trouble.
I don't see a good way to fix it, though. There are already so many 3-letter words in the puzzle, making the solve feel choppy, that the usual solutions — moving the black squares under ORI to the left or adding black cheater squares — would make that problem even worse.
I did like some fill — HUMOR ME and LEOTARD in particular.
It's an innovative concept, but I'm not sure it's possible to execute it elegantly enough to live up to NYT standards. I did appreciate reading Stu's thoughts, and how hard they worked in a valiant attempt to get there.
