Looks great. Yes, I use Brasso too. It does a great job. I also have been known to take out my Dremmel with polishing tool to get any stubborn rust off. The Brasso works best, though.
Enjoy your machine! Mine only does straight and zig zag as I don't have the embroidery attachment. I also need to hunt down the spool pin thing-a-ma-jig for the second spool pin holder.
