More details and refinements made to the undersides of the wings.

The Top surfaces of the wings are also worked on to bring out the details of the feathers.

This is much less noticeable here as the birds usually  keep the tops of their wings as sleek as possible to aid lift in flight.

Swift sculpture progress of second underwing

The Swift project continues...with more research and work on the underside of the other wing...it is a slow process to understand and represent/reproduce the wonder of the feather pattern and character of these marvelous birds.

The two wings need to be similar, yet not exactly the same.
The leading edge of the wings are being gently shaped, and refined, though they must be able to bear the weight of the sculptures and not be hazardous to touch and feel.
