Merging landcover and simplify geometry could decrease tile size and MBTiles size.
Landcover layer is now very detailed on zoom 8 and 9

We're using the default DP geometry simplification which create angular, chunky shapes instead of beautiful shapes.
Turns out newer PostGIS includes Visvalingam-Whyatt geometry simplification popular…

On lower zoom levels there can be artifacts on some roads (especially in mountains), we could use line smoothing.
