I am a full-time lecturer for pre-med students, which is more stressful than you can think and the only hobby that really calms me down is photography, especially landscape photography while wandering in the woods and mountains.
I would appreciate some harsh constructive criticism for my photos. :)
Overall, nice shots!
These photo's would definatly benefit from some post production work in lightroom, bringinng out certin colours you remember when taking them, emphasising what made that moment special.
On a more technical note, the first couple could benefit from being HRD images. A process where you put the camera on a tripod and take multiple pictures of the same thing with different exposure values, then editing them all together (Really simple to do)
