As I think you said the area of potential concern is the bit right under the TT which is a place where frames can fail sometimes.

How are you going to do the filing/sanding? I recently made a fake fillet brazed frame (TIG braze over TIG welds-- plenty of reheating involved!) and sanded/filed them as best I could but I wish I'd seen Paul Brodie's videos which hadn't come out yet. He uses a kind of christmas tree shaped thing on a dremel-like tool (his is probably air-powered) followed by a dynafile-style belt-sander. There was a thread on this recently but good advice is be super careful with the power tools not to gouge out the steel and if in doubt use a hand-file in the tighter spots.

The joints look pretty good to me but I've never done this style of brazing.
