@lynxster4, @Pixey, @Roger the Dodger, @Seerose, @Woodsy thanks for the reply and sharing your works.
@Ego Eram Reputo, @toe_head2001, @Eli, @Maximilian thanks for the rep points.
I am happy that we managed to get another tutorial out of the Graveyard.
Looking at the Seerose's images, I intend to extend this tutorial with some techniques and little 'tricks'. To do this, I need some time to experiment with images. As soon as I'm ready, I'll publish the second part of this tutorial.
