Very nice Robert. Seeing your work makes me want to dive back into film.
One of the benefits of digital is the ability to shoot a huge number of images without any shooting penalty, until post (spray and pray). But I have dialed back all my digital to single frame, (except for sports and very fast action), which has forced me to concentrate on timing/anticipation and composition. I am beginning to sharpen my eye and selectivity with single frame ... and maybe my next step will be back to film.
