I get where you are coming from but for me its not because they are furries its just some of the furry characters in their portrait art do not look very attractive at all. For example ignoring their personalities and their artwork for the sex scenes. I think 3 of the woman you can impregnate are not very good looking in their character portraits and its not because they are furries.
The 3 I am thinking of are Luna, Agatha and Astana all 3 do not look attractive as furries in their character portraits while I think major story characters like Evelyn are not only more attractive but you really bond with them over the main quest line it just makes me think why wasn't Evelyn picked instead if people want a furry character?
Also if you make the argument it specifically has to be a gnoll or the Lupine race I even think that Elvire is better looking than Luna (Luna has a way better personality though.) If you want an example of what an attractive character portrait for a gnoll should look like when compared to Agatha and Astana look at a character from a game similar to this one.

Furry charactes can be good looking and some of the furry characters we can't impregnate are better looking and have more of a connection to Kristan which is the problem. I am new to the game but did the polls even include an option for characters like Evelyn and Kailyn? This isn't attack just a wish that older characters who have been around for longer got more love and pregnancy options too. I actually liked Agatha's storyline a lot but if she looked more similar to the character above I would like her a lot more.
