Head Progression

I thought some of you might be interested in seeing a few of the different concept sketches I've done to try to figure out whet these river creatures are supposed to look like. Here are a handful of sketches I've done focusing on their head.



Here is a full-body sketch of the critter. This is pretty close to how I think he should look.


I apologize for the low quality of the sketches. My scanner is pretty old and doesn't want to cooperate with my sketchpad. :)
