This is Turtnail! It is an animal half-turtle half-snail inspired in Fool's creatures (like the Shoesnail).
I've taken his textures to create the face. Some of the colours are taken from his pics too (But I had to change the pallete in order to adapt it to this image).
I like the type of Fool's sprites and it is also inpired in his "rabbits" and their poses.
The preview is like one of his creations...
