Here's one I just finished. I was figuring out Daz Studio, and put this together with a combination of Blender, Daz and GIMP. Came out pretty good. It started out as a t-shirt, but it doesn't seem right for that. I think I'll make a postcard out of it. "Having a wonderful time, wish you were here."
Of course, now I have a b-movie hero, his girlfriend and the Party Beach monster (made the head myself in Blender, following movie stills), so I can do a few more things with them. Much easier than using just Blender for people, as I had been doing. I took a little bit of licence with the monster's body, but I didn't want it to end up looking too real, so I made it look more like a guy in a suit. Has to look fake to get the full effect. The 12 MP render of this is really something.
