hmm...how come I never replied to this thread?

Well, anyway, since you began this model, this is a great improvement! It looks grat as it is now, espacially I like the tale or whatever it's called....the texturing also looks nice! Maybe you can even improve it....maybe by adding a little specularity....try searching for pictures of crocodiles, delphins and similar creatures, to see how exactly does it look in under the sea/water.

Keep it going!
