JigSawPuzzle Design - The Riddle Part2

The initial image produced in part 1 is now going to be the image like a kid imaging all thoses mathematical constants.
The Puzzle should be the head of an african child (black, short curly hair). The face position is lateral. The head and neck and the on the top of the head the designer should place a cartoon box with the image of the part1 inside.

-----------------------------------------------------------------------------------------------------------------------------------
The riddle or Enigma consists of Mathematical constants, formulas and greek alphabet spred along the borders of the puzzle.

This project requires the designer to know about math.

It will be mostly black and White/beige.
Background white/beige
Letters: black, bolded.
Font: will vary;
Content: mathematical formulas, constants, greek alphabet.
as per Design specification attached.

formulas: bold
