Producing some beauty shots
Once the design is looking reasonable, I spin it around, trying out different Camera Lenses and angles of light, and moving the time slider to flap the wings. I find looking for cool angles is a lot of fun. I usually cover the illustrative angles first: front three-quarter, rear three-quarter, some interesting detail compositions showing parts of the design and then some action shots showing the ornithopter in different scenes with its own special modifications (see the next step).
