Julien explains "Deepful Meaning”; 

"This one is more about an inner trip, this journey in French is called "introspection," which is the process of being aware of one’s own thoughts and feelings and mental processes. 
A lot of black and blue in the foreground evoke some kind of deep focus to me. The wavy shapes on the background are a way to talk about interaction between things, people, situations or maybe my eternal obsession for space and time. On the far background you got these bright colours, like something is about to happen just as the anticipation of a great idea arising."
