When In Tropic Area

You can purchase this art piece at http://www.ugallery.com/oil-painting-when-in-a-tropic-area
I am also a professional CG artist at https://jaywonganartist.artstation.com
The artist tries to pull you immediately into this humid, hot tropic enviornment. There are man-made constructions surrounding those flourished plants, seems this is a view from a room of a local house.

No special processes or material used.
Varnished, the sides are not finished, just the raw color of the linen canvas itself. No wires.
