Looks like a few cold joints there. Using a clean hot iron, re-touch any solder joints that are not smooth and shiny.

Also, where the solder has balled up around the pin, it often has not properly wetted the pad. Re-touch those to make sure that the solder has flowed well onto both the pin and the pad.

use some sort of spacer, a visit to your local hardware store will probably help you find a few options!
