I've seen worse. It's just that your process was flawed. You need to tightly twist and tin the wires with solder, tin the contacts and then while holding the tinned wire to the tinned contact, apply heat with the iron to 'sweat' the connection together. Soldering is just one of those things that gets better with practice, like sex. I'm not going to make the analogy about riding a bike because once during what I thought was a successful date, I kept pedaling with my feet and still fell off. She no longer returns my calls.
