There's seven pictures, so I'll split this into seven posts.
The before image. If memory serves this was the first matte I worked on. I was still figuring out what I was doing with this one.
I got this done, and then went on to the next matte. I knew this was no good, but for the life of me, couldn't figure out what else to do with it. As I said, this was my first stab at it all and I still had plenty to learn (for that matter,I still do)
So I came back to this image having to put in a path, decrapify the river and make it work a bit more. I came out with this, still not completely satisfied.
When in doubt, smother with clouds. Between that, and fixing the colors, this got much, much better by the time I pronounced it finished.
