I really do like the more cunning and erudite version of goblins the game is going for, who also make for better protagonists (imo) than some low-IQ "horndog" version of goblins.
But I also understand the criticism that the women in this game do not seem too reluctant to join a goblin warlord's harem despite the people of the world presenting themselves as not too welcoming of the gobins.
Its also why I felt the interactions with Darcia were much more intriguing, since getting into her pants seemed like it was gonna be a challenge.
I'm not suggesting that the women don't put out at all till then end and you only get one scene with them as an "endgame" (like certain other games have done), but perhaps have the MC gain their favor through,
- Daily conversations. Which would flesh out the characters more with your (dare I say) exceptionally entertaining writing and would require minimal animating work.
- Giving them gifts. Which would also give earning/stealing money more purpose.
- And maybe a little side quest (akin to the MassEffect2 loyalty missions). Which unlock new scenes as you update your game.
