I think Sivir looks better with blue lipstick. It makes her splash art look more futuristic if that makes sense - more tron-ish if that makes sense - in other words, the unnatural lipstick fits naturally in the context of the splash art. I've also done a couple tweaks here n' there besides just the lipstick on photoshop because (don't get me wrong, the splash art is absolutely amazing and whoever did it should be commemorated and thrown a party and a raise) I think that Sivir kind of looks like she has a crooked or maybe really long nose (almost a wicked witch of the west nose); naturally, a change in the nose and perspective of it also changes the shape of the face slightly so the lower face has been altered to match the correct perspective in congruence with the nose.
Ultimately, I think the change in lipstick color and darkening of the top lip (which would actually happen IRL since the way lips are curved and from the light source, the lips would appear darker at the top than the bottom) makes her lips also look fuller and well... sexier.
I'm not a Sivir fangirl of anything of the sort (in fact, I don't even play league anymore, I just browse the forums ^^) and maybe I'm being a nitpicky b!tch, but I think the changes make her look more bueno. Feel free to agree or disagree, but that's just my opinion and maybe others of you might agree with me. Have a nice day!
