edit: im no good at critique, maybe later tonight when I have more time
#1 looks like an over-processed under-exposed image, with some strange exposure artifacting going on the back of that guys hoodie.
#2 dig the colour and mood though i feel like it lacks a subject and a purpose. If the subject is the rock, whats the purpose of shooting that rock in relation to the background and why do the rock and background work well (or not so well) together?
#3/4 looks like some portraits to me.
#5 dont really have an opinion on this one
