I recently released two asset packs on itch.io:

The first is a collection of nine fantasy-themed backgrounds--see below for a few examples (scaled down). All of these backgrounds have dimensions 2560 x 1440--save for one, which has dimensions 2560 x 2560.

You should find them here: https://thaumaturge-art.itch.io/assets-fantasy-backdrops​

The second is a set of fantasy-themed UI elements--press-buttons, check-buttons, some cursors and heart-icons, and a few other things besides. Once again, see below for an example image (again, scaled down).
