Hello ,,and welcome,
I find the red streak in #1 draws you to the fella,nice touch.
IMHO would look better as a portrait,
#2 I like the pathway leading you in, I find my eye stops at the lake,
The marmot is brilliant! very sharp,and nice bokeh.
Nice sky in #4 I find the trees draw me to the centre,witch is rather plain.
#5,,the pebbles draw me in 2 the centre,and I cant seem to find an apealing way out,maybe crop some sky out.
There,s some interesting light going on ,,nice dof,
Nice images ,would like to see them after you edit.
