This one is off to a great start! As I've said, Slip Gun is one of my top favorite JT Edson catfights, so I'm glad you're bringing the essence of that excellent catfight to art life. I'm fine with the slow buildup, it establishes background history and the strong dislike both women have for each other. That builds great tension and gives meaning and fuel to their fight. You had that same strong personal connection with the Zora vs Vida gypsy catfight remake. It's missing however in the Cavewoman fight because you chose to go with a generic representation of the era. While the artwork is excellent, that makes Cavewoman less interesting for me. But know I'm excited about Wild West Catfight, because of the storyline and connection to Slip Gun. I'm looking forward to the next update already. If you don't post here, I hope you do post it on DeviantArt (I've seen your new site there) or maybe consider using Patreon. I follow a couple of excellent catfight art and animated catfight artists there. Your work is so good, I'd be happy to pay a modest monthly fee to support your efforts on Patreon.
Those familiar with Slip Gun should find this fight all the more interesting. The underlying theme in that book was about the long history between the two women and how it comes to a fever pitch in the hotel room catfight. I'm sure you'll do that fight a real justice. I can see these two women fighting all around the room with complete abandon, up against the walls, bumping into and falling over furniture, and maybe, unlike in the book, tossing a chair or some other object at each other. Just don't let them pick up that hammer and try to use that, it wouldn't fit with the rough and dirty, but fair, nature of their intense contest.
