Been hard at work with this all day and the modelling and texturing is just about done now. Painted the Diffuse map, reworked the Normal Map a little and finally got my head around Specular Maps.
In total i've spent about 3-4 hours modelling the base shape in Max, another 3-4 hours creating the higher poly version in Mudbox and then around another 4 hours painting and texturing it. Its starting to look pretty cool now. If I can be bothered i'll be rigging it next, then maybe creating a scene with a few of them swimming around in a tank.
In the mean time I wanna do a decent render then touch it up in Photoshop.
