Nice capture - just a compositional suggestion, when using things like the path, try and position them/you so that they lead into the image, rather than out as this one does part-way up.
I can answer for me. Almost all the edits were just Levels, Saturation by channel, and Brightness/Contrast.
The reason that one area or "clump" of trees looks cookie cut against the sky is that after I used the Color Selection tool I forgot to shrink by 1 and feather by 1.
Looking at it again now I'm thinking it needs the bottom cropped off too. From where the lower seam of grass/walkway exit the left side of the frame, on down. Oh well, maybe Bill will do it?
Doesn't do it for me. I'd go wider with less of the current foreground. But then i don't know what's to the right. Might be goblins or a landfill. So to rephrase, if possible i'd go wider with less of the current foreground. Also move a bit left and try to get the path going out of the shot rather than tease us. That's just me though.
