umm i agree the bushes are way to sharp the look sorta like billboards i proffered the original render.
i think the bushes are to vibrant and contrast to much with the organic greens and plus you vary rarely
see bushes so far into the Photoperiodism process while the other trees are still quite lush in colour.
to make it more natural i would either make the trees leaves more yellow so it looks like they are starting to go through the Photoperiodism process or make the bushes leaves green in colour so it fits more in with the time of the year this render is set

p.s just shows you what a little postwork can do to a scene

i love the soft aetherize effect of the second render it just looks sooooooooooo much better than the stock

but i am one of those guys who loves post work

oh and would you be able to post the specks on the grass and one the tree leaves i realy want to know how you got those leaves to look so realistic!
