i've been contemplating my previous post and might had underestimated the task in hand. it was mentioned earlier about yukikaze's horns. then i'll add the kongou sisters and the mechanical_halo tatsuta are wearing. in short, even without showing the ship's arsenal, there are still enough remnants to associate the namesake ship. and that should constitute more than half of kancolle already (unlike the destroyer girls particularly the akatsuki sisters which are more like school children). then it might not be a worthy endeavor at all.
how about limiting the personification tag to copyright in-universe non-human or non-humanoid character? that would make post #1512867 easier to locate a canon non-human character.
for original or IRL, aside from the personification tag, it might be necessary to add the ship type (battleship, cruiser, destroyer, submarine, etc) and the ship namesake if identifiable.
applying this to kancolle, most ship girls will only have the personification tag if they share the image with their namesake warship.
regarding mecha_musume, i'm not sure atm. at one side, strike_witches mecha_musume only has 6 pages. or are they different? on the other side, i would consider mecha_musume something like a magical_girl. so as long as it's fully clothed with sufficient display of firepower/armor, i may consider it as mecha_musume?
thoughts? thanks.
