"Attention, these are from our game but might not reflect the quality or the final outlook of the game"
While that may be true those environments were not developed by you. The Future city screenshots are from a asset pack on the unity asset store.  https://assetstore.unity.com/packages/3d/environments/sci-fi/scifi-neon-city-118580
And while I can't find anything like the grass lands environment I would not be surprised if that was stolen as well.

Why are you being dishonest? Is there nothing developed at the moment that you can show?
Investors beware.
