I compiled the original picture with the two traditional version I made and used various photoshop tools and techniques to make it into a cohesive picture of a mossy building with an old forest having grown around it.
This is a scan of another printout of the building that I put onto canvas paper with matte medium and painted over to give a . texture of moss on the building.
This process picture is a scan of a printout I made of the original picture with the background removed so I could sketch and figure out what I wanted to add. The picture has some high contrast edits to turn the picture into linework to mesh with drawing better.
