A sculpt/sketch I did of a Rahkshi in zbrush. It was partly based around several sketches I did where I attempted to conceptualize the process of how their armor was created that is, kraata being exposed to energized protodermis to form the shell, so I used the kraata as inspiration for the armor and opted for a more organic look given their nature. (P.S. Zbrush now has a 45-day trial version, if you guys are interested)
