Nice pick you've got there. You should really put a serious finish on it thou. (e.g. with 600 grit wet/dry sandingpaper). Make sure all the edges are smoothed down properly. This will improove the performance of the pick alot.
I also agree with SFGOON, regarding the hook. You really need some hooks and/or half diamonds. They work as single pin rake and as single pin pick. You will find yourself opening almoust any lock with a nicely shaped hook. I had great results with a FALLE style deephook I made.
Don't forget to check out all the nice DIY picks on this forums if you need inspiration. And check out the HOWTOs on finishing picks, and of course pyros video on pickmaking too.
Keep up the good work, keep pictures comming, and of course keep picking
