I am happy to answer questions ... except I don't know the answers. Forge of Ice is a one-man band in Alaska making great quirky models and he told me he is currently desperately trying to fulfil an overdue Kickstarter which has been delayed due to recent events, and then these Shadow Apes will be part of a range of beasts and characters coming out (hopefully) before the end of the year.
Don't know the sculptor, but they're very nice aren't they? They're big old boys, standing 40mm tall and a great mix of chunky musculature and delicate details. I thought they'd do well as Yetis as well, strangely enough, but also any kind of alien or supernatural heavy, depending on the paintjob.
EDIT: Also, one more thing (don't know if this is important or not), they come with separate heads and a hollow in the neck to glue them in. This allows a wide range of head positions and it's a good snug fit, not needing pinning. I did use some putty just to smooth the join though, otherwise there would be a deep crease round it. Not the biggest modelling job in truth, and I'm sure it's not something to make anyone clutch their pearls, but I thought I'd share.
