Dear Rudy,
thank also to you for writing.I take a look at your website and I see a lots of very interesting digital sculptures rather
than your works are related on characters creation;I usually are more abstract oriented
Concerning the workflow for these images the most part of them are create with IMM brush (insert multiple mesh).
Exported and imported in Octane render with some HDRI images as environment,some tweak on material…et voilait…
