These first three show the different bump maps I have been experimenting with to see if I can create the right type of sand along the sea bed.
I think that the subtlety of the last one will work the best especially because I will also have the light from the refraction of the water playing across the bed as well and I don't want it to detract from the viewer's focus on the character.
These two different forms show the work I have been doing on the rock cave that the creature will first appear out of. The left is a harsher version of the right but I think that this suits the character's mechanical nature and will probably continue down this avenue.
