Sketch dump 01

Here's something I've never showed before. These are rough idea sketches that I did while working on something else. Each usually takes 15-20 minutes, just to get the basic idea down.

After that, depending on whether I think it's an interesting enough idea to develop further, I may go back and finish a few of them later, or just leave them in the dark forever~

If you can make out what's going on in these super rough sketches, which one would you like to see finished ? Give me the number :)
