not bad for the materials that you used, however this is exactly why you should use the right materials: a good, quality solder and kynar wire.
there's a ton of flux residue on your solder points (since you weren't using the quick solder points, it was unnecessary to completely fill those two holes with solder).
and because you used 24-28awg wire with plastic insulation instead of 30awg kynar wire wrapping wire, the heat from your soldering iron shrank the insulation leaving a lot more of the wire exposed than necessary (which can result in a short occurring between one or more of the other wires).
My 3rd wiikey quicksolder install. First tin both the points on the chip and the wii board, then lay it over the points, tape it down, solder the 2 big points, take off the tape and solder the remaining 4 points. works perfect
