clearly visible IMHO... heavy sharpening in post?
mrbig is niggling, but he is right.
Particular in your foreground you can notice some jagged anti aliasing caused by sharpening filters.
If you insist of using them, (everybody has his own opinion) try sharpening an additional layer and spare out jagging regions and keep them as they are.
Especially in the foreground this might give you a little illusion of depth.
