Hi
My name is Mihajlo Petrovic.
Well,your comic examples are doing digitally.I dont work in digital formats and do not use digital programs for drawing and painting(only in postproduction retouch,Fotoshop for example).
But Im very skillful comic artist who paint and draw traditionally free hand with using of art materials such as(pencils,ink,watercolours,gouache,tempera etc..all on very quality watercolour or pastel paper).
