I think you did just fine with your sig.
But to seriously answer to you trying to help improve this game, well you can't, not much in reality.
Though HS and HS2 offer a great variety of adjustments to create a good female model ( the males one still require works imho) the models are still bound to looks like those in the japanese anime, so certain features like the boobs for example can be tweaked to an extent yes, but they always will have those anime proportions and would looks a little unrealistic ( or completely exaggerated like in other games made with the same game/engine I've seen here).
Also you always need to consider that it's Caribdis the creator and if he think they are ok well they are, we can't do nothing to try to "help" him, in the end it's his creation and he do everything according to his own artistic vision, not ours, so even if we can find some things not to our liking, well we can only bear with them and continue play, personally I find them more than acceptable.
