I agree that it currently looks like he has two parts glued together, but the look I am going for is that of a sinewy, flexible creature. If you look at the most recent side veiw, you can see that the torso has a sort of an S-shaped bend to it. If it/he were inflexible, how would it eat it's prey? I was thinking that for the charge animation it actually would drop down on all 8 appendages, but I'm not sure about it now..
