I can't see the solder joints in those pictures.
Here's a picture of some soldered joints. The one marked with a red "X" is not very good.

Only the ones with a green check mark are good solder joints.
The other joints are probably working okay but ideally the solder should look like the ones with green check marks.
It would help if you could take a similar picture of the joints on your board. You need to use a lot of light in order to get a good photo.
