Question to a professional is my game assets to heavy for a game.

Greetings i like to get some feedback and tips f are they " “to heavy for professional game asset creation”? Should you only try to use planes and rotate them around with textures when you create grass and plants?. i find it very hard to get planes to look good.

Looking at some " quixel megascan models" i think they look realy messy, and from what i understand is that they promote it as game assets for triple A games.
Would you say that my models would count as “low poly”? are they “ok”?

You can try reshading your textures with a darker colour,
that which the colours can add even more realism, and take away from the low-poly look.
