The markers don't show it as well but the chest is pretty transparent with the light shining throughout it while the rest of the body is more opaque. The tail and spines on the back are made of energy and stone with different colors/tones of autumn.

Finally figured out how to draw a golem The design of the stone body and face/head can be altered if needed to look less anthropomorphic (more rock-like), fit magistream lore, or be more unified or whatever but this is a pretty good idea about what I have in mind for the creature. The old version can also be a reference, I just wanted a better depiction of it.
It would be a very tall (and kinda bulky) creature and I had thought about drawing a small bird perched on it's hand to show it but I didn't get around to it ^^' The left arm I accidentally positioned weird and had to make it transparent/disappear so you could see the design of the tail (it would have been blocking it) but the arms are pretty much the same on both sides. The leaves on the feet can be smaller if needed to help portray the size but I didn't have the patience to draw a bunch of tiny ones. The red crystal is actually inside its chest and shines through as a portion of the chest is mostly transparent but it could also be positioned to be on the chest instead if necessary. The trees growing on the shoulders have autumn/changing leaves on them but do not necessarily have to be thick with leaves (since some are falling off). Overall I hope this gets picked if only so they can draw/design a better style of stone body then me Golems are tricky...
