The lighting really adds depth... the light on the upper part of the tree (left), the lone guy on the right, the smiling phone lit individual, the background... did I mention the light.
I like the compositional work on may of the photos (e.g. By the lake - color with people walking)...
The rice terraces remind me of the Batad area in the Philippines... here they look steeper with a much larger community in the valley. Were you there for the terraces or trekking... I guess both. Definitely need a guide and I like her costume. I would have anticipated to see more rice plants in the terraces...
The mountains are wonderful... the family crossing the bridge on their bike look a bit cold, and she carries an umbrella...
The "grandmother", daughter, and child is a nice portrait...
I can relate to the hotel life after trekking
Looks like you had a great time... beautiful photos...
