I am experimenting with how to take picture of objects like some of you have done. Using daylight usually is the best for me, but it, like flash tends to blow out. Here I used the on camera flash...but lol, I put a plastic storage container in front of it to diffuse the light. As for the "sculpture", I give small, cleaned, marrow bones to my squirrels to gnaw on to keep their teeth from over growing and to provide them with natural calcium for healthy bones AND teeth. They chew on them in various directions creating interesting designs ( at least I think they are interesting :-)
Kind of looks like ivory carvings to me...
