[@Gisk] Looks good to me! Feel free to put her into the Characters section once you get Spice's approval. The power level seems fine, magical girls in this are meant to start out reasonably low level and gradually get stronger, so Tsutomi could make fairly small, simple devices at first, and learn to create more complex ones over the course of the RP.

As for pictures, how about something steampunk styled, like one of these?

[@DrowsyPangolin] Ooh, very unique! Again, she looks fine, now to wait for what Spice says.
