Tried it, briefing was good but completely quiet, i know some maps add random quotes from the character in question, don't know if that would be fitting here. Good length but a summery of the objectives in the end would be nice, you can't skip it in order to view the screenshots about the characters. You could also consider changing the colour of the screenshots to 'Terran Green'.
@SoulFilcher: Go
I took one but i assumed you were just interested in lower resolution ones.
Edit: A suggestion for the skip button would be that it replaces the 'Replay' one while the briefing is playing.
