Ruined walls (of a watermill)

Old ruined walls of a watermill like structure in Hungary, scanned with an A6000 for some photogrammetry practice. The water wheel and a large iron cog connected to it didn't came out right in the scan, but I might modell it by hand myself in the future for some Blender practice. One of the corners were covered with ivy's. Tried out handheld shooting with this scan and got some good, stable results with carefully controlling the shutter speed. The middle section of the building was filled with brushes and shrubs hence the messy texture. There were also a lot of holes on the ground, I fixed them in Blender by inserting and aligning a simple plane over them with vertex snapping enabled for a better fit.I also run it trough Instant Meshes and finaly retextured in Agisoft in the end.
