Stunning photos. Love the depth you get into them. How many lights are you using there, on the Jones pics particularly? I see a top light...I would presume three lights in total?
I've been experimenting with (cheap) lighting set ups myself for figures...using two hobby flashguns on ceiling rails at the moment, but I have a third as a spare.
That Ark is foo*** amazing, did that come with the figure? Wow. If it did, then that's worth Hot Toys money. Crying out for a dio, with a face-melted Toht and everyone.
