As I'm continuing work on my new asset pack - Sunnyside World EX - I'm starting to remake more and more of the old assets as well as just expanding on the (now free) base asset pack of Sunnyside World. The new biomes I'd already created (and will be coming as a final free update to the base asset), I'm also remaking from scratch for the new paid asset pack. So even more items in the new one will be completely new.

You can see a preview below of new-new land biomes. The example below is made using auto-tiles, so if your software supports it, you'll be able to draw landscapes with ease, as if using a brush! and if not, you can still quickly create something awesome.
Next up I need to refine the vegetation and other decorative land items before moving back to creating the other new game assets.
