Hi Stevan - I've mixed feelings about these, since they were obviously shot with intent instead of just being 'snaps', which makes you a photographer instead of just a casual snapper.
Technically all except the second are terrible, and that needs a good cropping off the bottom to help with composition. Is it useful to go through in detail for each image, or can you spot the flaws and issues in each for yourself? What sort of camera did you use (phone I'd guess) and do you have or are you interested in controlling stuff like exposure etc?
