Substance Designer Critique needed

CUBEBRIX

Hi there this is my first post on Polycount and decided to dip my toes in water and put my personal work out there. I would like to improve my skills and I will only be able to do that with input from other people so here it goes.

Here is a few Substance materials I have been working on.

Looks really cool! You're cobblestone's albedo is too dark imo. Most of the time, colour brightness should sit near 50%. Keep it up!

I think your materials could benefit from some better Albedo colors. The red brick especially feels overly saturated and contrasty. E.g. more like the Albedo here: https://www.textures.com/download/3dscans0115/132042

Thanks guys. I will play around with the Albedo maps and values and post an update.

Here are some updates I did on the materials above.
