I See London, I See France

I'm still trying to decide which setting to send Duck and Ladybug to first (character names still pending as well).  But, I have been working on a few pictures.

I'm pretty happy with how they've turned out, but I still need to do the inking.  While this is all by hand so far, I've been thinking that I might not want to do all the inking by hand.  It's a pretty permanent thing.  Watercolor can be softened, blended, or covered and pencil can be erased, but you're stuck with the inking when the pen hits the paper.  So, I'm toying with the idea of a computer program so I can do the ink work that way instead.  It would still be by hand, but I would have a little more "oops" room.

Also, while the scanner and some adjustments to brightness in Paint.net have helped to make the colors pretty true to the in-person paintings, I'm wondering about using a camera instead- taking a picture of the art and then transferring the photo to the computer.  Does anyone have experience with this?
