New PBR Textures in development

Hello there,

I want to show some new PBR materials I made for Unreal Engine.

20 years ago I already made plain textures and high-quality 3d multiplayer levels for the Unreal Tournament series (Unreal Engine 1 + 2),
and now, after a ten years break focusing on digital photography, I want to get back to content creation for Unreal Engine 5.

I am no professional, I have a full-time job that’s not related to design at all, but I always spent my freetime on developing further.

I am a photographer and I create seamless photorealistic PBR materials out of my own photographs.

Here are some pictures showing recent displacement materials I made. Most are 2k one is 4k.
I cannot really estimate the quality of these materials as I had a break of several years from development and design (focused on photography and family the last years).

Is the quality ‘good enough’ to sell textures like these on Unreal Marketplace?
What do you think? How do they look?

Here’s a link to a youtube playlist showing some of those materials in motion:

Any feedback is welcome!
