seen ur work for modeling challenge
its very nice
i saw a textured image
u have textured it in zbrush only
or with casual way by unwrapping it.
I did'nt unwrapped it as the challenge was exclusively for Modeling and sculpting . I used polypaint option in ZBrush to put some color variatio and used a material tso it look like skin.But before polypainting you can Group UVs and that can be done in ZBrush . Texture>UV>GUV tiles however this is not the right way You in to lay down Uvs in 3rd party package for generating Diffuse Map later or any other map. I guess i am through.
