I quickly created a random landscape in Artrage. I started to feel it becoming very lacklustre, so decided tweaks were needed.
I opened the image in Paintshop Pro and made a few tweaks, adding clouds, the Sun and a few birds to bring it more alive.
I tweaked it some more in Paintshop Pro, altering the colours slightly.
I then edited the picture in Photoshop Elements, and tried to give it an almost old-fashioned photo feel.
I then toned it down slightly. I think the last three versions are my top three.
