So while I've been waiting for things to render etc, I've been reading through the user guide for Color to see if there was anything I could do to further improve the results I was getting. As it turns out the way I was achieving some of the colour corrections was not the best or recommended way but then I guess thats what you get when you don't read the instructions, so I went back, initially to try and modify the colour grade I already had however in the end it was easier to start over. The following are screenshots from the first half of Star Wars using this new grade, let me know what you think. :)
