I don't know how to give hints on this one, but it's a game of rock paper scissors with paper at the top, scissors at the bottom left and rock at the bottom right.
Lovely picture, but not logical. And REALLY difficult.
Spoilers: There are eight free-floating pixels in this image. That is, pixels that have white squares to the top, bottom, and both sides. Those pixels are R3 C17 R18 C19 R19 C20 R20 C5 R20 C17 R21 C18 R22 C16 R23 C17 Tested, with these pixels filled in, the puzzle is logical, and quite fun 8D
