'A thin blue line' is an idioma in Eglish, theres a film with such a name... and its initially referring to british troops that bravely standed at the way of enemy, if my memory doesnt fails me.
the blue tint and contrast is nice, but i did not like those photos mush. it looks like rather a tele-lens playing process for me, then a decent result that speaks to me.
ps. but judging by the upvotes and payout those are great photos and brilliant clicks! :P
