Lock

I'm still going through the generic icons and I hate making locks. This one took me way longer than it should have and I still don't like it. Feedback is welcome. :(

I had a small discussion about this on Twitter. I'm at about 45 icons right now, I'm thinking about getting to 50 and then I'll make it available for you guys to buy. Then update the set regularly in 5 icon additions which will be free for the people who've bought the set already. (Think iconjar by @Liam McKay :3)

As for the price... I'm thinking about a £20 ($30 I think). Thoughts?
