Fighting Tutorial in Assassin's Creed

What do you think of this one? There will soon be a next part, and one thing I intend to change is the grey background. I'll replace it by a SVG drawing. Transparency isn't an option because there is no video material I could use behind, and reading and watching at the same time is something at least I aren't able to do.
