Most of the fwooper portrait icons show the bird´s face straight from the front with light coming from the right side of the image (lest from the perspective of the bird itself)
It actually looks like they made one picture of each gender and recolored them for the different color-variations.
Just the pink male pops out of this, it is shown slightly sideways and the light comes from the other side than all the others.
Why is this one so different?
