A more detailed feather based on “Solid Noise”

Settings:

I stretches this texture horizontally and multiplied it with the black-and-white image of my feather’s silhouette. After this I created a “New Layer from Visible”, box-selected the left half of that feather and did some strokes with the “Warp Transform Brush” on that selected in order to bend the fibres upwards. After inverting the selection, I repeated this on the right half of the feather.
