I like the first one, i would emboss the jigsaw pieces a tad more and leave more of them missing with a coffee table under it or something to emphesize the consept a little more. I like the font aside from the K in Krypto.
both are alright, but i don't like how his head is perfectly centered in the first...it should be about 2/3rds of the way up the photo not right in the center...looks misaligned
