There is a pack on smutbase labeled "good dragon dongers" would be good for dildo models or alternative futa mode options, not sure how difficult they would be to reskin to match the various dragoness skins though. also suggestion of a vaginal licking animation (or bj if futa mode on).  A zoom ability or slider  for the poses mode. I've listed many suggestions in some of my previous comments, I just really like this game, it satisfies scaly cravings
