I found that too, but it didn't seem up to the usual quality of WotC concept art so I thought it might not be realI always found that looks too much like an Easter Island statue. I can hear him just say "Give me gum-gum, dum-dum!"
Btw, seems WotC already planned on introducing Primus earlier into 5E. I found this concept art from Conceptopolis. From 2018, so unlikely to be used now.
