Like the second and third ones. But perhaps you may reduce some filters you've applied because they look a tad overcooked to me.
I'm not sure what you mean.
The log in #2 and #3 looks at me as if it was treated seperately from the background by a mask which doesn't fit properly. But maybe it's just a jpeg artifact caused by compression. Or my old eyes which can't cope with hard contrasts anymore.
What was the shutter setting for the second shot?
