You can change the tag back, but I think it's the other way around, where it's Sena cosplaying the female protagonist for Pokemon Go, not vice versa. The title of the picture "トレーナーの星奈ちゃん" makes me think that it's Sena as a Trainer, in this case.
No you're right. It's just late and for some reason I just reversed it.
Wouldn't a "Error" tag be enough then? Certainly, if this one was flagged for missing (or forgetting to draw the rest of the leg), then all of the arts with the "Error" tag should be flagged since they all have defaults too (like 6 fingers or a bust that seems reversed etc...).
Error tags should not fucking matter there is a reason why it's a tag and not a guideline for do not upload. Tony Taka is fucking infamous for fucking up certain body parts, but you don't see people flagging his shit for that reason. Some people flagging for the stupidest reasons.
Anyone is welcome to change it if they disagree. No cameltoe, no sexual pose ( I mean I dont watch ballet much but this looks like something they do normally) I just feel it's safe.
Well I believe the artist used to post a lot of the art of Nico instead of Pixiv which is browsed by less uploaders. I don't think the amount of art made is any different.
