>will this work

no
about 1/3 of all the joints appear to be ''cold solder" joints
meaning it appears they're connected but they're probably not
i've circled a few in red
the blue ones have too much solder
when they look like a ball, it can mean that the solder didn't wet the joint, making it suspect

your problems appear to be: bad solder, lack of flux
