And because my brain can’t let go, here is a standing stone concept. Obviously would be in Vadim’s colour palette if modeled. Similar colours as the rocks I mean. The red is mostly to help see the carved detail.

And while I’m still on this Easter egg fixation, there is always the far simpler option of some one modelling Loki’s mask from The Mask(1994) floating down the stream or hidden inside the house. @dostovel So that would give you 2 Easter eggs in 1 object:
Loki and Jim Carrey.

Hopefully know my mind can rest and return to more important things 🙄
