side ponytail describes it as "tied up and secured away from one side", so either I don't think it applies here or we should broaden the description.
low ponytail and hair over shoulder work, though I feel like this particular style is common enough that if it doesn't have its own tag yet, it should. (See: the whole dead anime mom haircut thing.)
Need a second check if these are greyscale or grey theme, some areas like the skin seems to have some degrees of variation instead of flat out the same tone.
Probably as good of a place to ask this: is there a specific tag for fan created characters? For example, omen_seeker_(darkest_dungeon) is not an actual darkest_dungeon character.
Some art may depict original subjects alongside subjects from an established copyright, or a fan-made character of a specific copyright. In this case, the art should be tagged as original and with the tag for the copyright.
So just use the copyright tag and original, there is no singular tag for the concept (that I know of).
Just to be safe, should I keep the arttag to posts? It's a brand, everything uploaded was drawn by different illustrators. I could also tag official art because of the copyrights.
