Applying final effects

I use a custom brush to create subtle air particles and a soft Airbrush on a Multiply layer to vignette the image. I copy merge the image and run Filter>Radial Blur>Zoom (at three per cent) with the centre point on the drone to create a subtle camera movement. Then I choose Filter>Lens Correction> Custom to add Chromatic Aberration and finally Filter>Noise (two per cent).
