I'd say the improvements are significant: Cropping and color adjustments + losing the fog definitely work.
Not sure I'm sold on the simulated lense flare, but maybe I found it a distraction because I had my 'critical hat' on vs. how I might have reacted had I not seen the original.
To begin with I thought you may have introduced some "fall colors" to a few leaves, to which my initial reaction was favorable... then noticed the flare continuation near the bottom foreground. Definitely not a showstopper by any means.
Anyway, my .02. Glad to see you found us!
