New Kaiju Designs

These are several kaiju designs that I just sketched out. Mainly, this was done mostly for fun, as I have no clue what direction I want to go.

1) A bipedal Crocodile-like monster based off of Zilla.
2) Quadapedal reptilian monster cross between a turtle and a stegosaur.
3) Insectoid/reptilian looking monster with a tri-jaw and a bunch of attitude
4) A winged bipedal hairy insect-like monster with scythe-like hands
5) Bipedal burrowing worm-like reptile with scutes on it's back (the artist formerly named Gezion)
6) Aquatic reptile monster
7) A Godzilla-like monster with two crests on it's head which contain a glowing organ within it.
8) Ape-like dinosaurian beast with a Amargasaurus-style twin sailback

Now, who do I like so far? I'm leaning towards Kaiju 7, he looks like I could have some fun with him.

Feedback is welcome
