It is really disturbing how many people automatically go "eww, you're such a pervert" to posts like this.
Is there a difference between wanting a champ to have a larger (or smaller) top/bot vs wanting softer (or harsher) facial features? Only if you make there be a difference. It's just physical characteristics of a fictional character, and there's nothing wrong with wanting the character to be more in line with the original artwork/depiction(as OP pointed out in the linked past post).
Wanting stuff to be consistent is NOT part of being a pervert, if you think it IS then YOU need to fix yourself.
Though in all honesty I think the SG artwork is fine? It is not nearly as skinny as the left side of the photo indicates, at least not on her wiki or official Riot page. But if it WAS as skinny as suggested then I'd be agreeing with OP as consistency is important. I checked side-by-side comparisons though, her thighs seem to be on point.
