I have no idea if you wanted this to be offending or not, but in any case name me ONE cosplayer that looks more in the face and expression like Riven? I think that is why this picture got popular, because it was taken before Riven was popular for her bunny skin (only), because you would never imagine that others skins exist (even). Also I atleast made the effort to create a specific makeup look for the character and I take my time to create it every time I portray her. And please notice that I haven't mentioned that this photo is a cosplay one, have I?
I didn't say you were cosplaying. I'm referring to the many comments of thirsty males about this being the best Riven cosplay and that other Riven cosplays pale in comparison. A lot of these comments are from 2013 and 2014, when photos of good Riven cosplayers were also posted on this site. If you search even earlier than I did, I wouldn't be surprised if you could find cosplays from around the time you posted this too.
