I liked this one a lot, but I think the brick count and cost is too high for what it's trying to achieve.
This was my favorite (realistically feasible) Minas Tirith set I've seen: https://ideas.lego.com/projects/36275
Maybe it should be sold in 2 or 3 sections. The architecture (up-close) may not be as nice, but the overall effect is perfect!
I think Eowyn, and the Witch King/Fel Beast battle could be it's own set--and maybe combined with or in addition to an Oliphant scene for the Battle of Pelenor Fields.
Here is a good Osgiliath set: https://ideas.lego.com/projects/141244
