May I suggest that you clean away the solder blobs on all of those pins (solder sucker or solder wick) and re flow them
Agreed, the excess solder makes it difficult to properly inspect the joint.? You only need enough solder to fill the joint, ideally the outline of the wire and the terminal should be visible.
Here is a link to a NASA spec, with great color photos of good and bad joints.
Of course we are not building spacecraft, but there is a lot of hard-won knowledge there.
