You just need lot better 3D art
Some users like Loopix have done great contributions like very good trees to use directly in 3DGS.
For the models , if you search well in Contributions you'll find bettter things for grass and trees, try some sites on the Net, you'll find very good free models also.
Same thing for textures, there are very good ones you can find on the Net for your terrain.
A7 should be selled with quality textures (like Unity engine) instead of 10 years old ones
This way we should see lot better Showcase, even made by beginners !
