It fits the image set rule better: Drawn content that does not constitute a comic or cg set (e.g. loose images, screenshots, image dumps, etc.) Images within such galleries are preferred to have a singular theme (e.g. singular artist, series, character, or fetish). The Non-H rule mentions nothing about the commercial status of the gallery. This just happens to all have the same artist. It shouldn't have the 'artbook' tag either despite the commercial status.
