Yes, very nice! And a great idea to use the individual strands from some stranded wire... I might not have thought of that myself.
Here's my very first try at replacing a "large" surface mount chip, some years ago. It's a motor controller from a Celestron CGEM telescope mount. I had to replace some entire traces, as you can see, using #30 wire-wrap wire. I did use the "Chip-Quick" stuff to get the old one off. Probably still used too much heat since traces lifted, etc.
But it works! Still using it in my mount, although I have a complete replacement new board in the drawer, waiting for the next big failure....
