Wing layering
An angel reads first as a winged figure, so the wing must carry the stencil. Stencil viability comes from a ranked feather family with open skin between primary rows, not from drawing every barb a photo shows.
Check: Cover all but the longest primary feathers. If the wing still reads as a wing, the layering is sound and inner rows are support. If it collapses into one paddle, the wing needs fewer rows before anything else changes.
