Well, I think your day shot and night shot are quite ok, except you atuned it towards red colour. Your day shot is underexposed by at least 1 stop (for the day, most probably the meter has been fooled by the light amount of white light). For The night shots, taking out the composition, the exposure seems to be just about right only. Don't mind the very reddish sky, Singapore sky is polluted, thus you will never see true black colour in Singapore sky.
I just adjusted the day shots by levelling it up by 2 stops and remove some red, staturation and contrast and all those artifical post processing only makes it look artificial. I personally felt your orignal pictures seems to be more natural then ESPN's artifical version, especially the day pic.
The night shots are quite ok, just mind the composition. For landscaping, normal 1/3 rule or the rule of the golden separation applies
