The only problem is that she didn't remove the gun barrel from the turret housing, so I'm not sure how she is cleaning it with all the armor plating in the way.
For those wondering, this is a remake of one of his old pics and the location is actually a navy museum where one of Mutsu's rudders is on display, in this picture she's mounting it back on the shoes.
I changed the parenting because the images seem to be straight re-uploads of the twitter image to pixiv by the artist, with the slight difference in file size because of pixiv re-encoding the image.
Thus, in terms of both compression guidelines and first-to-the-post relations, I'm sure the twitter images should be the parents.
Edit: That is to say, the artist is not uploading the source image separately to twitter/pixiv, he's uploading the twitter image itself to pixiv.
So from this point onwards it should be considered superfluous and not worth uploading pixiv images without a significant size upgrade, if not outright spam?
