Found the portfolio of Robbie Trevino and was intrigued by some sketches he had done of the organic fleshy creatures. "Arms" here has some elements of tech or what I perceive as metal and flesh as well as what appears to be stony/rock-esque peaks. Laid out the base of my sculpt in about 4 hours. Next up is the detailing pass. Will gather all my thoughts into a final video at the end.
