How Jonathan Maurin created this sci-fi landscape
I began by creating the composition. I made the structure with the Lasso tool, and the gradient in black and white. I then worked on the values. The darkest parts and the more blurred areas were to create a focal effect.
I refined a few elements in the bottom of the picture. After I worked on the texture of the building to give the image realism, I added a new layer with a clipping mask on each plan and drew lines using textured brushes.
The colourisation was a difficult step. I created new layers in different blend modes: Overlay, Multiply, Screen or Color. I chose an orange/yellow colour for the surface exposed to the light, and a purple colour for the area in the shadows.
I added some details, such as lights on the moon, highlights on the buildings and the clouds, and more contrast. I refined the character. I cropped the artwork to enhance the size of the buildings and give a feeling of vertigo.
