B - looks to be cold or disturbed while cooling.
C - the wire appears to be sitting on top of the solder.
Neither one is good. I'd put a bit of flux on the wire at C and reheat it so the wire is IN the connection. Let it flow so the whole terminal gets heated, and don't touch it while it's cooling.
And then do the same thing to B. The terminals should be smooth and shiny, with the conductors definitely secure.
There is a lot of solder debris left loose and terminal "A" looks a little shabby. The debris is solder balls and a large one near R27 at the top of the board. Add flux to A, B, and C and reheat. Other than that not too bad.
Looks better. It's hard to tell when I zoom on the pic because it gets fuzzy but it looks like the gap between the two points at A could be cleaner. Curious...what did you just bridge? An amp I assume?
Kidding aside, soldering on a circuit board is almost an art...takes a lot of practice. I built many kits over the years to learn the right way to flow solder onto those leads. Even whan I was a youngster I still used a light with a magnifier to really be able to see whats goin on down there.
I'm 54 have not soldered since @19 was good at it but threw time, hands shake and eyes go bad and life is limited from age and other things so doing best I can.
LOL!!!
