The head style

So this is spinoff of my skillup journey (6.5 day). I was sleepy all day, so I decided not to create another training lineart but make decision what art style match to me and match to "project". So, I decided that using more chibi-like heads is more interesting (but I need to fix how it looks straight and in front sides), also I think that using pop-artstyle will allow me get to my goals.
