I didn't really want to go for a brighter sun because I wanted to keep the romantic sunrise feel; even though sunrise is a bit more pink than this. I certainly experimented with it but I couldn't find a balance, I still wanted it to feel as if the colors would change significantly later on the day. As for the lens flare / effects, I hadn't thought of that - I usually never put them in because it would suggest a camera point of view instead of a person point of view. I tend to avoid camera 'artifacts' like curving and flares. But it might've added something extra, sure
