Time to publish something, since I haven't done it in ages :)
I decided to finish up one of my substances and present it nicely. The idea was to "model" all of the details on a basic sphere and tessellate it.
UV distortion on a sphere is reduced with panorama node as well as curve addon for Substance Designer (that's why textures have crazy shapes on it). Wings were separate object (planes with alpha) rendered separately and blurred in Photoshop.
C&C very welcomed :)
