Well, I'm not sure how much my opinion is worth because I'm just as new as you, but from what I can see, I would try sanding/polishing the business end a bit more. From the reflection on the pick-end of the tool, it seems that it's not quite as smooth as you might want. As others on this board have said, and as I've found to be true myself, the smoother and more polished the pick, the easier it will move in the lock and the more feedback you will receive.
Just my $0.02
Good job on it though, I need to start making some from hacksaw blades myself. I received some street-cleaner bristles from Spossum a few days back and I need to get on those making some more bogotas; too many locks to pick and too many picks to make... never enough time
