I get the feeling this art is personal, clearly representing a duality of emotions and suppressing them, putting on an appearance of happiness. That is just what crosses my mind when I see this. I like the simplicity of the black and white motif but I feel the brush used for the outlines, text and background masks at the top could use some stabilization and perhaps a glow effect, at least for the left side as it seems the white is supposed to be a sort of aura around the character. If the idea is for the lines to look wobbly, I would recommend another, denser brush and then turn down the opacity to have a uniform shade alone the entire line but still give it that ethereal appearance. I really do like the characters design and feel like the strongest linework is on the drawing on the right. I'd like to see this style experimented on and refined over time! Overall: interesting concept and character design, would like to see more experimentation.
