Handar, the blog idea sounds really cool, but at this point in time at least, I don't think I'd be able to do so (I've tried a blog in the past just for general LEGO things, but it's very hard for me to keep up with something like that on a regular basis). I'll definitely keep it in mind, though.
And Gecko.. A drawing of a Skull Twin you say? Hmm.. Ok
I don't have any of the minifigs myself, but fortunately 4 Diamonds let me make the drawing from a photo of his.
PS- I know it isn't Castle, but hey.
