Thanks everybody. Glad you like this!! ^o^
KSHA : I intentionally make the shot a little bit over-exposed, such that it look more vibrant. And of course, it was taken few weeks ago, next time I will try what you suggested : f4 apperture
Kenny : I have tried different white balance to take the same shot. Given the yellow lights at the far end of the background, I choose this bluish WB. Anyway, thank you for your comment!!!
