This is the Hunger Games' Mockingjay pin.
There are two versions: the main photo is the revised version. The other photo is the initial version.
About this creation
The main photo is the revised version of the original creation as seen above. I switched the angular bricks of the original version which held the body of the arrow to upright holders so the the body of the arrow is completely visible.
Why is the arrow gray?
I didn't have enough yellow bars to make a yellow body of the arrow, so I went with gray.
The body is held up by angular bricks above the mosaic so it can travel across without any trouble.
