Yeah, just treat the wing like a living surface. Start with a high‑res feather brush, hand‑paint each feather with a tiny ridge on the top to mimic the natural micro‑bump that cuts drag. Keep the ridge thin—just a few pixels—so it’s almost invisible but it moves the airflow smoothly. Then paint the leading edge a shade darker than the rest of the wing; that gives the illusion of depth while actually smoothing the pressure curve. Finish with a subtle, almost imperceptible wash of a darker tone on the wingtips to help the vortex form. Trust me, the real magic is in those micro‑details that you see only when you zoom in; the eye will think it’s just good art, but the plane will thank you with less drag. And if you’re feeling rebellious, slip a tiny wrong feather somewhere—just to see if anyone spots it.
