yea too much solder and it looks like the solder cooled while you were working still or not enough heat applied, usually forms weird peaks and non smooth look, sometimes it may look like its attached but isnt by just melting the solder on the wire instead of heating both the pad and wire, kinda looks like lead free solder in a ways, they require more heat and are harder to work with. ever since i converted to lead free alot of joints look so damn noobish. should lay out the wires flat, tape them or glue them. from the looks of it though it looks ok and would work fine leave it alone if it works.
oh also too much wire is exposed least enough for it to short if moved wrong
