Nice, thanks.

Lots of assumptions need to be made. Thanks for the puzzle, though.

Need to test your puzzles first... when you go to save it, there's an option to try it.

Blocks of 5 on each edge are logical, and one other square, but the rest is just guesswork.

Pure guesswork.
Make the circle for the face, then the left eye is easy. Then guess the diagonal line on the right eye.

The diagonal goes from center to the upper right side.
