A number of concepts I made while working on the game Snake Rivals, that I later modeled and textured. The shots taken in Unity feature my models and textures, as well as the awesome animations made by Stuart Holgate! :)
For the Slime Snake I made a custom shader that includes a fresnel effect, something we didn't have in the game before.
I didn't end up doing the model for this one so I won't include that, but it's a fun concept!
Bonus: Shadowfire Snake, featuring a custom shader I made that combines a scrolling alpha texture with a gradient so that the bottom is always opaque. And a custom ember particle!
