Just loving what I do.
As Avid is made for fast cutting I would advise to use the overlaid keyboard as well, it will save you a lot of time in the edit (memorizing the keyboard is another option).
Unless you have a lot to show use 2.35:1, for example big action scenes etc. When close to characters narrow down your width as you would achieve a better result, since the subject will take more space in your shot. Audience will be less distracted from what is happening around. 1.85:1 could be another solution to achieve a more cinematic feel than 16:9.
I don't understand why a technical achievement in Photoshop is considered as a kickass poster. In my opinion this poster looks very much alike anything else you see besides the fact it "looks" illustrated. Which in my opinion doesn't capture the feel of the film. Moreover it guides you away from it and romanticizes it. Crucial to a good poster is a moment of the film captured within the poster. For example have a look at American Beauty and The Shawshank Redemption.
