@BobbyS I have a confession to make. I nicked your mugshot sheet idea. In my defence, it's too good a concept not to!
Started a sheet of point and click adventure game characters at Cardiff Film and Comic Con yesterday, though only got one character on it. Manny from Grim Fandango by Jorge Molina (£15).
Also got an Usagi sketch by Stan Sakai for £55. While he was doing it, he was telling me that he's off to Japan soon to research an upcoming story about Christianity coming to Japan, which sounds like it'll make for an interesting story.
I went by Doug Wheatley's table as well, hoping to get a sketch, but he was already half-doing one and fully distracted from that talking to another guy at length about everything from movie production, celebrity culture, realism about what you can achieve in drawing etc so after marvelling at his original art pages (including the original for that famous Vader Nooo! page, which is fantastic) for a while and getting drawn into his talk for a bit, I cut my losses and made my excuses to go. Fantastic artist though - the shading on his pencils is unreal and he showed a "rough sketch" of Conan he'd done on the train over which was amazing.
The convention as a whole definitely felt like a business exercise compared to something like Auto Assembly or a local con - all the comics guests were hidden away on the top floor (where I got lost - twice!) with very little signage, while the main floor was given over to dealers and actors (most of whom were rarely at their tables, from what I saw). The "comic zone" felt more like a hang-out spot for cosplayers than anything else.
