One of my first digital paintings.

The idea of a city in the near future. A tree at the edge of the world is already half a robot and feeds the city and flying transport with its energy.

As an artist for me is quite interesting to look behind the scene and to have a look on how everything starts. Below you can see some of my sketches to this artwork, my composition research, line art and close ups.
Hope you like it, let me know in the comments. :)
