These are photos of the printed copies of Marguera Blues which you can find at some UK Comic Fairs, in Alita Comics (A Coruna, Spain) and Zaza Comics in Venice (Italy).
Once I had the idea of the story I wanted to tell, I sketched all the pages with pencil to develop the script and to make sure that the narrative had rhythm. I also did studies of the characters, locations... These are sketches of the mutant fishes:
The next step was to draw the actual pages and I used blue mechanical pencil on A3 paper. Then, I inked the drawings by hand using thin brushes and Indian Ink. Instead of inking on the actual drawing, I made a copy of it. I wanted to keep the blue drawing clean and safe, so I inked on a very light blue print. You can see below the sketch, the blue drawing and the inked page.
I scanned the inked pages and coloured them digitally in Photoshop. You can see the colouring process in the screenshots below. I start with flat colours, then cel shading, lights, a few details and ready!
