Congratulations—you've soldered the resistor to the board!

If the solder joint doesn't surround the entire lead, reheat the joint and add more solder.

Check if any solder unintentionally bridged with a different joint. If so, carefully use your iron to heat the solder between the joints and separate the bridge. If the bridge doesn't want to separate, desolder it and try again.

Like any skill, practice makes perfect. If your first solder joint doesn't look picture-perfect, that's OK! It takes a few attempts to get the hang of the movement and timing.
