Cheers.
The thing with the bushes is, they're meant to be yellow. There's a very common plant that grows in woodland/rocky areas, I don't know what it's called but it's the yellow things visible in this photo taken in my home town...

That colour is a hard one to achieve. It gave me a real headache and I knew it would be the main picking point on this image. When I leaned towards the reddish-yellow it didn't work, even worse than this greenish-yellow I ended up with.
I might do something with it, cheers, guys!
