Siyok - Iterations

Iterations based on silhouettes from the previous post. Again I will see which my peers think is the strongest.

Im leaning more toward the characters on the bottom as they have more of the bottom feeder look I am after. I reckon itll end up being a combination of 2 of these iterations as individually they feel a bit bland.
I have to mind making the character too complicated as it is for a comic rather that a game so will need to be redrawn numerous times and remain consistent.
I am still not convinced with the spines and sails running down the upper back of the characters however I do like the idea of the bottom half of the back featuring some kind of structure to aid in stability and extra thrust when swimming.
I still feel that the large protruding lower jaw of the top group gave more of a slow whitted feel.I chose to split the chin and jaw. The thinking was that taking this feature forward could mean the jaw could open vertically as well as horizontally.
Character 5 appeals to me as the low set eye gives the impression of a whale but the shape of the head and mouth looks more like a whale than a bottom feeder which makes me think of a more intelligent, good natured character.
Like the silhouettes I found myself spending WAAAAY too long on these for what I produced.
