Ok, now you're cooking. Great pics and poses in this update. A few favorite pics are 56, 57, 62, and 65. You've stepped up the intensity level and have done a fine job of creating the savage and animalistic style of a real cavewoman all-out brawl. You've achieved this using a lot of face mauling with both hands and feet, and with inhibited, all-limbs involved, twisted body positions. Congrats!
I like your plans for a 2 Days in The Valley motel room catfight remake, the western bedroom catfight (which sounds similar to JTE's Slip Gun fight), and of course an epic gypsy fight showdown part 2. One additional suggestion would be for a mature women battle of some type to please us older guys.
I understand creative blocks. We all get them on something or other (like me on backyard projects). Focusing on something else allows the cobwebs to clear and the creativity to return. I'm not sure where you can go next with Cavewoman, other than full nudity of course. Maybe they could fight over the spear for a bit (no stabbing though), or their movements take them to another part of the cave, maybe with some shallow water. I'm sure you'll figure out some very good action.
