I also don't think it's appropriate to use the NSFW tag for artwork unless you want it to be regarded as porn. Out of courtesy, you could put a note in the post title about it containing nudity, and then avoid using a nude in the first image of the post, (as others have suggested,) and then put any content you would like in the actual post.

With all of that being said, it is the Internet, and there are plenty of trolls that will happily come along and flag your content with no good reason.

I didn't know who Aleah Chapin was until today, seeing your post, but that piece above, It Was The Sound Of Their Feet, I've been googling to find something more written about it, and this has revealed interviews and general statements on the purpose of the piece, and more about her work, and one video interview with the artist where this piece is explained. However, I'm left wondering if something was left out in the discussions and explanations I've seen. Do you know if there is any special significance to the posture, position, or body language of the two figures on the far left? Or do you have anything more about this piece? The other women in the piece are engrossed in this childhood game, but the two on the end, even though they're all nude and all physically close, and all the others are engrossed in this game, these two are almost aloof, and staring off, possibly in their own world, or perhaps they're facing away because they already went through and their detachment has some other significance? Their embrace just strikes me as different. I'd appreciate any comment you might have on this.

Thanks!
