Yep, will add them in the future.
Currently I have planned to:
-improve the trees (delete the old ones + add around 15-20 new ones)
-improve the bushes
-add more and better grass
Unfortunately it will take some time till I will post those updates, because currently I have no possibilities to create textures for those assets (atm we have around 30-60 cm of snow :p) but assets in a higher quality are in progress.
