Can't really say its wrong, but I probably would have laid a small jumper wire in the solder puddle. Probably the biggest thing you are fighting is making sure the copper trace on the board is really clean.
Don't know or presume to know your soldering skills, but most people grasp the heat concept, but not necessarily the cleanliness. A good clean iron tip that is pre-tinned with fresh solder is just as important as clean connections. Having anything "dirty" makes it take longer before the solder "flows" properly thereby increasing the risk of heat damage to circuit traces, glue, or components.
