I will revist this though just want it clarifying so I fully understand mate
I can't spend time marking every point, but like I said, get a good magnifying glass and have a look at each one of them. Unless they are not looking like the one marked A in that picture I posted above, you have to redo it. Most of the ones I have seen in your pictures (not only in the one I linked to) are bad. If you have a ball it means the solder wire did not melt and floated out, or there was dirt on the surface or the iron or you did not heat up the wire you solder AND the surface you solder it to and so on... Just google "how to solder" and you will find millions of answers regarding soldering with pictures and Youtube video, so I will not go into more details.
