When making the floppy itself thinner you forgot to adjust the small holes depth. They are too deep. The arrow should be one pixel deep, these two bottom rechtangles differ in size. Normally they go through the floppy but you could apply a bottom for the left one. The sticker looks weird. It's placed in some kind of hollow but at the edge it's thicker than the floppy. The metal sheath is too thick and it looks like if it was lying on the floppy's surface but it should wrap the floppy.
