Ooo, very nice :3~~ I especially like the first one, of the dog - almost reminds me of Tramp from Disney's Lady and the Tramp... he's cute ^.^
I always thought pastels look nice, but I've never really delved into 'em - just here and there in art classes past, and I have a set of them, but I'm completely hopeless w/ them

Your pics look great, what kind of paper do you use when working w/ pastels? And any kind of tips you could give? :3
