This is a creature inspired by the amazing art of José Garcia (www.artstation.com/garciartist) which is a character designer-artist that I really love the work. I urge you to discover his job if you don't know him yet.
For the creation, I decided to not follow exactly the original concept by adding some new details on the character like the mushrooms on his neck. I sculpted it on zbrush, and I made the render using 3DSMAX and vray. For all the texturing process I used Substance painter for textures and little skin pores.
I hope you will like it, and stay tuned for next works !
