Hi mike, I am currently doing some rigging practice on two characters, (doctor said I am not getting enough rigging in my diet) but when I am done, I think I might squeeze myself into the Sea Creature Challenge. Here is a peek at one of my characters, I animated him using the most primitive rigging setup ever (moving FK joints only). Now I am tryng to wrap my head around a more advance rig setup using IK handles and grab icons.
