Alien Head

 The zbrush alien head was perhaps the most interesting task for me personally as it really gave me the freedom to determine how the beast should look on a purely diffuse level, it harkened back to my old days painting plastic models and my gaming days with the Warhammer 40k tabletop game. There is not really much to comment on in terms of technique as I more or less stuck to the spray brush and occasionally dabbled with the colour spray brush and finally I used a cavity mask to reinforce the models shadows and really make the texture pop.

I went for a style rather remeniscent of the General Grevious character from the film Star Wars Episode III: Revenge of the Sith, with the boney exoskeleton seeming to hide or guard a fleshy and more organic interior and I actually referenced images of him to get some of the finer details and skin variation to look authentic.

Finally I exported the polypaint from Zbrush as a diffuse map using a UVed low poly head in Maya, that combined with a lizard eye texture taken from the internet and a normal map created in much the same way used Xnormals it created a rather convincing looking low poly version of the high poly zbrush mesh.
