Gothic Temple Environment Unreal Engine UE4

A small scene in Unreal that I finished these days during quarantine... Some things could be certainly improved, however, I feel it's time to put this baby to sleep. I would love to read some feedback if you have the time :) it will be very appreciated.
Thanks to this fellas for their feedback which helped a lot :) Alexis Fioretti, Maximiliano Dajtscher, Ariel Anabitarte and Otto Ostera

Final render.

Full environment.

Bricks/Stone wall texture set with and with out snow.

Bricks/Stone wall texture set with snow. Adding some stucco and layers of snow by Normal and AO map and a world position damaged effect.

A trim sheet, same shader options than the bricks one.

The brick wall shader allows me to paint different texture sets, add a layer of damaged, add snow (depends on the Z Axis, Normal map and AO map), and the common tweaks like tile, contrast, normal intensity, etc....

Altar low-poly + normal map.

Altar + normal detail layer and it's snowy shader.

Some blocks low-poly + normal map.

Same blocks + normal detail layer and it's snowy shader.

Cross. Low-poly + normal map on the left and full shader on the right.

Some basic hanging snow/ice shapes... snow blending, normal detail, fuzzy shading, etc...

Foliage sculpted in ZBrush, baked and textured in Substance Designer. Ground materials created in SD as well..

Some variations of the tree shader with a few snow piles. I created the 3 Tree materials in SD.

The shader I did for the trees and foliage allows me to paint different texture sets, add a layer of a peeled texture, add snow (depends on world position, Normal and Heighmap map), and the common tweaks like tile, contrast, normal intensity, etc....
