So far I haven’t had any problems sharing this artwork but I’ll ask just to be on the safe side. Also, I wonder, do I have to tag a post as NSFW if it contains a link that leads to a NSFW artstation link or would it be better to note this before the link?
Also here the references
So when you “ask” this… because you do want to be on the "safe side:…
…in a hidden area…
?? Or… this is just cick bait 
…for this… i do not think so… but others… 
… this is a weird world…
If you question whether or not to add a NSFW tag, it is better to just include one… then you’re covered either way…
I would just say, before the link., that it leads to NSFW content…
As long as the link doesn’t add a NSFW Thumbnail…If that happens to be the case Use the Statement as the Optional Title in the Hyperlink…
