Lol. One of your favourite characters too! Nemo was the first film I took my eldest boy to see at the cinema, it is one of our favourites and he will still sit down and watch it with me (he's nearly 11, lol).
For me, this time, the mesh was so frustrating... I don't know if it was because I was trying to fit it in between client work, I was tired, not paying attention or what, but I could not get the polys to work for me. Ended up being 3hrs of modelling, which I am not happy about as that is not a difficult character. I need to learn to stop zooming in and out all the time and just get on with a base mesh and look at the detail later. All started from octagon.
Steve, what did you do to avoid 5 point pinching around the edge loop for the fins?
Oh well, on with the next one.
Here's some nice hi res reference images if you need them for texturing -
And some wires (animated gif) and a render -
