great details!
Here is a blender flower with high quality details.
Quads count : 156,962
Rendered with procedural materials that are in the blender file ( this is why i suggest to use the blender file ), it do not countains texture maps and it is not UV unwrapped.
These procedural materials are made for Cycles but can be modified to be rendered in Eevee of course.
Also the .fbx and .obj file formats don't have hair system as shown on pictures but the .blend file does.
Thanks.
