Hi All
Have taken this in the morning. I am attaching both the snaps (Original and post work too). Please give me some improvement areas. Will be really helpful.
Post work:

You worked on it in post, yet you failed to straighten the horizon line, which is crooked in the original, visibly so, and stayed crooked in the edited form - why? That'd have been the FIRST thing for me to change, as it is quite distracting, both in the original, AND in the edited photo. And this, even though the edited version now longer has a horizon. And yet it strikes my perception as "wrong" immediately.
