Good set Stu
#1 Is just lovely.
#2 Excellent composition; could've done with more DoF and/or a bit of sharpening.
#3 Is beautiful. You are so good at capturing silky water. Love the compo, colours + soft focus, and the exposure is spot on.
#4 Love the colour of the sky. Excellent exposure, compo + viewpoint.
#5 Yep, nice one too.
Summary: All very good, 1 + 3 are stunning.
