I've created it using ArtRage-Studio, a software that simulates different painting materials.
At first I painted the canvas with some water-colours and then added huge piles of oil-colour.
Then I took some virtual brushes and then I spread and mixed the colours.
After that I added a new layer and covered some areas unsing virtual felt-tipped pens.
Again I started to paint on a new layer to add oil-colours on top of the felt pens.
This had been the last stage before I started to add some depth and details to the image.
Here is the final image again (so you don't have to scroll up to compare).
