Sunset at University of Sydney

I always wanted to take some photos with sunset view in the university. However, I seldom go out during evening. Yesterday, I went to my friend's house. On my way back, it was sunset. Although those photos taken almost at the same time from different angle, the colour of the sky was totally different. I know my photography technique isn't that good, but I still try to capture some of the sunset view. Perhaps next time I can capture a better one from different location in the university with different colour of the sky.
