Slanece, I have a bit more time to comment than I did earlier today.
Once more, hot f-word stuff! I especially like Cross35; I like views from behind the cross, primarily because I'm into comely female backsides.
If I had any suggestions, they would skew towards my ideas about authenticity. Habitués of this and other crux sites already know what those ideas are.
Nail your victims' feet with two nails rather than one. Nail their feet higher up on the stipes. And nail them to short crosses, the "crux humilius." That was probably the most commonly used, which put the victims at eye level and "up close and personal" with abusive guards or onlookers, and ultimately wild animals looking for lunch.
None which you need to do! These are red-hot crux renders on general principles. It's unlikely that the feet were fastened with a single nail, but what the the heck? Most folks of European descent grew up with traditional depictions of the capital-C Crucifixion, and I'm convinced a lot of folks into this kink are in it for "the blasphemy component," a naked woman crucified in the manner of Christ.
Further, the "crux sublimus" was probably used often enough with high-profile executions. A common slave would perish anonymously on a low cross. The execution of a prominent criminal or traitor would employ a high cross, and be like unto a public service announcement: "WHEN YOU REBEL AGAINST CAESAR, YOU'RE IN FOR THE HASSLE OF YOUR LIFE."
I attach two images. Windy is one of my favorite imitation-of-Christ images. World of Hurt is from our resident engineer Jedakk, who's calculated the physical stresses of crucifixion, and what is possible and what is not. The luckless lady is nailed according to those calculations. Windy is impossible.
Feel free to ignore them there calculations. "This is fantasy, careless product of wild imagination!"
Slanece, I welcome your renders, and the numbers 32, 33, and 35 make me hope you have many, many more in queue.
Carry on, good sir.
