The full request, by Bruno, goes like this: A majestic dragon next to a lovely fairy. The dragon holds a rose (in his mouth or with his claws...) and the fairy is leaned on him. Together they watch elves dancing in round from the tune of a couple of celtic musicians. This scene would take place on the Pink Granite Coast (located in Brittany. Cf. Perros-Guirec, Ploumanac'h, ...) at nightfall with a sunset over the sea.
So, about the process, I did some sketches for the dragon and the fairy, drew the whole drawing on a A3 paper. And then added the colour digitally with the Procreate app.
