bubble c4d. good placement. there seems to be no light source really cuz of all the "shine" from the bubbles and it messes up the depth a bit but it looks good
I really like the focal, you showed it quite well. Hard to tell without actually seeing it, but it seems like it would look better in color. Nice C4D placement, and blending. Well done man!
It's a stock. I can't remember where I found it... My current sig is a stock and render put together.
Looks cool, though lightning could use some work, and all effects around the character makes it really chaotic ...
