She's mostly ready now. A bit of weight painting to still be tweaked, but this is more or less right. This is the model as it is more or less, with no effects other than Maya's basic viewport.
She has an interesting little Point Constraint setup for the eyes so that they operate in tandem, but on opposite sides of the head.
I need to find some decent subcutaneous reference of dolphin skin for a subsurface scattering map.
Going to teach myself some animation skills and how to use the Maya playblast, and then it's onto some space dolphin clothes!
