Hm. I liked Lord Hedrisil. Felt like a good wholesome character even when he was casually fucking the brains out of people. Also liked your ideas with how you interpreted Kamek. Always did like Small Dom, Big Sub.

A standout character...I'm a bit indecisive, so I'll name a couple that occupy my headspace.
At the top is probably Nozzy and his Nergigante posse. I'm a big fan of Monster Hunter and anthro MH monsters, and far as 'dommed to dom' stories go, I love his progression into the monster he was meant to be. Nero, Neyard, and Nexis are also pretty great.

Other characters that come to mind are Krevshankus (Scrunched Ball) with his hypnotic jiggly cheeks, Clethus (Fortune Favors the Horny) and Hulk (SB again) providing good food for navel-fuckers, and Bruce because I'm weak for Zekrom anthros and big subs, and you did both. There are more, but I'll cut it short before you're left with a laundry list.
