I'm only new to this site, and I am only an ametuer at best but i like #1 it has great colours,
#2 isnt doing anything for me, way to dark, doesnt tell a story.
#3 is a great waterfall shot but the highlights in the top right hand corner is a little distracting.
#5 Shows good motion as the wheels were spinning during the shot, maybe lighten the dark shadows in the helmet?
#6 Man your lucky to have those lights where you are, is it the northern lights or something like that? auroa borrialis
??? I dont know what they are called
