Dirty Window

I posted the dirty window on reddit and people had some questions so I am posting more images here. Last image is the photo I took of the window I used for a reference.

wood textures were taken from the source photo.

wire and clay modes

The photo I took for reference, this window came out of an old falling down chicken coop on the 1st property my husband and I bought more then 20 years ago.
