Balaji,
I agree with the previous comments. The sky appears to be very blue. Reducing the saturation will help.

@ sign infront of names makes it impersonal, as if a person is compared with inanimate objects. Not sure why @ sign is used by softwares these days for tagging. To my mind, and to lot of people that I have talked about it, the @ sign gives an impression of price as we have learnt during our college days. If we don't use the @ sign while speaking face to face or talking over phone, then why do we do it online? Best is to just use the name for addressing as wel do in real life.

Cheers,
