Great to hear. While I always welcome getting more traffic to my blog, it is only because I want other serious Trekkers and film-production buffs, modelers/etc. to be aware of the high-resolution scans I purchased and try and make available digitally for use by them on their projects and works.
As to tag naming, that of course that all depends on how you want to categorize or structure things. You know way more about the ebb and flow of content here than me (being basically a newbie).
If you make a new tag I would maybe suggest something along the lines of “original production drawings” or perhaps “filming production artwork” or some such thing.
I lean a little toward the latter which implies that this is about “official filming production” pieces/posts as opposed to original works created here by community members, which are “original” but not in the sense of original to Paramount, etc.
My thinking at any rate was that it would be inclusive of concept sketches, production drawings, production/set blueprints, matt paintings, etc. from the filming productions (television and motion picture).
