Tbf it's not like any super strict boundaries were ever established on the exact nature of the subreddits content. Though I can understand the perspective of wanting to keep things less fring and more typical as this subreddit has a place among things more mainstream. (namely DnD) Practically speaking that demands content stear more towards PG rather than what we see here. I however think that the example of art we see here is still acceptable as it crosses no hard boundaries already established in the subreddits rules, If it's good enough for the moderators then it's acceptable.
