Flail Snail from DnD

I thought they were cute, so I wanted to sculpt them.
The concept for the shell can be found here: https://boards.fireden.net/tg/last/50/51947703/
(link doesn't work anymore, but I don't know who the original artist is, please let me know!)
First set rendered in Iray using a custom MDL I made just for the shell, the 2nd set rendered in Marmoset
