Lock please!

To be quit honest i wouldn't buy it. Its hardly visible and something most users could do themselves with a simple painting programm. =/

I have to second . You can hardly see it and it's not that great of quality. Perhaps work on your technique before you decide to start charging?

I wouldn't either :( However, it looks like you have some potential! I'd say if you spent more time on them maybe, you'd have something cool :D

tbh no, most of the lines aren't even connected and it looks like sloppy work. I would consider if the lines weren't broken and the picture had a better quality.
