Tianmen Shan
Located in Zhangjiajie, China. Tianmen is the name of the mountain, shan means mountain in Chinese. The mountain itself is one of the most popular destination for tourist in China because it has the longest cable car as transportation and a giant hole on the top of the mountain. The photograph of this mountain was taken at 2017 by me when I visit China last year.

Original image

First draft of the postcard, just using the photograph and adding some texts on it. 
For this image I want to tell the readers so they would have motivation to do something better.
Figure 1 : Before applying filter
Figure 2 : After applying filter
These two (Figure 1 & 2) were made after I received the first feedback about ecotourism critique postcards and changing the text. But in the same week another feedback was given by Eduardo about the art deco. So I tried to change the second one by giving some filter to the image (Figure 2).
I also changed the text because there are so many greenery around the mountain and I want people to imagine what if these greenery gone in the future.
Figure 3 : Changes of text and fonts
Figure 4 : Further change of fonts and the money
The last 2 changes I made were done after in-depth research about ecotourism and changed the whole text and by adding some money to reflect what does the text means. 
But because the first image (Figure 3) didn't really blend with the text, I changed it so the money will act as leaf of the trees in the second picture (Figure 4). The reason I change the text and adding some money is that I want people to think more about environment than economy because if the environment is destroyed we may not see it again in the future.
