Adding movement with weather
I think that the shot is coming together; however, it’s a bit serene and not the hostile wilderness I envisioned. I try to give some movement by introducing weather with wind, clouds and snow effects. I paint some additional drifting cloud shapes that succeed in framing the foreground, and drifting snow on a separate layer using the Motion Blur filter giving the layers a clear sense of direction.
I add some final detail to the vista including additional architecture. Darkening the transport helps the eye pass over it, while warming its materials helps it feel less monochromatic. I add a slight vignette to the borders of the image and finish the image by tweaking some of the edges. I soften some edges using a Smudge tool or Mixer brush to diminish distracting details.
