Cool find, going to come back and edit this once I see if it works in 1.13.x +.
EDIT: Tested in 1.14 18w50a. The lake and the savanna is now a small bay and is four hundred blocks off spawn. The desert village is now in the exact opposite direction, 300 blocks west.
EDIT 2: Second village + buried pyramid due west of desert village, and witch hut northeast of lake
Found a dungeon while mining, although I'm playing this in hardcore and do not have full armour or lots of torches so I didn't enter it yet. Apparently, there's also a fossil and possibly a mineshaft back there. If you're playing this and residing near the swamp hut, it's likely worthwhile going after.
Cool mountain area with the location from the screenshot about 200 blocks east from spawn with desert village right next to it.
