I love the clockwork key! The style of the figure has a very old-fashioned-children's-book feeling to it, as though Charlie is trapped somewhere further back in time. I suppose it does take him a while to grow up, if the way he spends some of his days is any indication. :D I like how his chair is tilted back but his pose is relaxed - not at all in control but pretending to be, is what I get out of that. I am also impressed that you took on the challenge of creating digital art for a piece despite it not being your most familiar medium.

The fic is really great too!
