I have changed the font size for a few times to see how it works with the image. The idea itself to impose a key word onto an image is not new but I just like the feel the text goes together with the image. Maybe I need to find another idea, however at this moment, I want to test this idea with different options.
I quite like the small fonts, as it gives a sublime feel with the sky image. Sky is mysterious full of potential and infinity. The oriental culture believes everything is governed by the sky so it is a sacred object in the culture, but creating smaller text rather than the big ones, could convey this super nature power and mundanity of the human culture.
