ok this helps looks moore like a monster ! from the above picture it was hard to identify what i now believe is the tentacles ! I Think it would be alot cooler if you repositioned the eye at the moment it distracts from the form a creature with one eye would need good visoion being able to see all around it I think they would go muc better either just in front of the two fins or above the mouth but thats a personal style and where concept sketches help issue it will be a little easier to see whan you get the mouth done try and refrance some squidd octi and shark it might help you with anotomical issues keep us updated
