This is Lehn’s very first concept.  His hair took a couple of tweaks, but it’s been basically the same since the beginning.  His uniform, though, that took some ironing out before I was happy with it (and as you can see I’d originally designed it to be about twice as big as it should be, because I think I was planning to have him inherit it or something… I don’t really know, that was a long time ago.)  He also started out human, and you can see his name had no h in it at first (I kept mistyping it with the h, so I gave up after a while and kept it that way).
