Views are easy: the other question hit the "Hot Network Questions" list 21 hours ago. Yours has not.
Downvotes are a little tougher: even we elected mods cannot see who downvoted your post, nor when the downvotes came in (so as to time them against the comments the post received). But the commenters left some obvious reasons they might have downvoted your post. So there's some guidance there.
One other thing jumps out from the comments: the one you left at 14:57:53Z is rather dismissive, if not plain rude, toward commenters who are presumptively trying in good faith to help you. Again, I can't know if anyone downvoted you in response to that, but I suggest you try and find a way to be nicer to people trying to help you. I wouldn't be surprised if you've generated some animus there.
The patrons themselves provide the last obvious difference between the two posts. The other post is based off of a well-known and established part of D&D lore, the Lady of Pain. (And as some comments make clear, the enduring lack of 5e's support for Planescape/Sigil/Lady of Pain material has some stackizens particularly enjoying that post.) Yours, by comparison, is tied to an "great lord over the chaotic Undead" that readers didn't get much direction from--and some of them told you so. It's not too hard to imagine that "people like the Lady of Pain more than your undead lord" accounts for some of the difference.
