Various pieces of concept art have been made and released for characters and objects within the Toaru series, most of which can be found on Haimura's website Rainbow Spectrum (and on here). While many characters have had concept art done for them and released, there are still plenty which haven't.

My question is this:

Out of the various characters and stuff which haven't had concept art yet (so far as is known), which ones would you like to receive it?
