Sorry, I have expressed my thoughts badly, because your report left me without words, disappointed and distracted. I was thinking on creative expression and imagination, not on design skills. Skills can always be upgraded, but creative thinking is something that you were born with or without.

So If I use any of the designs you mention, and put one more circle above, it wouldn't look a like "flying person". There are a lot of differences between the dimensions of individual parts of the "person" inside (arms, legs, body), as expected, because shapes you decided "that I am copying from", were not designed to represent human body, like mine was.
