I can't tell whether or not the artist is a beginner or not(only read chp 1 so far, dunno about the pilot), but I do know I love the way the art is drawn. Features like the nose definition and the curves of the eyes and face feels perfectly balanced and neat. I also love the over-exaggerated drawings and styles. Certain aspects kind of reminds me of Shinbo's works(Bakemonogatari, Zetsubou Sensei, Maria Holic,etc). There is a bit of inconsistency in the boldness of those lines, but I don't have much issue with that; just an observation. The backgrounds are pretty lacking, but that doesn't bother me either(again, just an observation). All in all, seems like a great start in my opinion. I enjoyed the story enough after the first chapter to want to continue. I just hope the writing can keep up with the art.
