Great tutorial (I learned something new -- the "snap camera to view" shortcut).

Just to add to Phil's remarks about Luxrender -- not only does it basically produce great results without much fiddling, but a lot of special effects (notably caustics) that are horrible to get right in normal renderers "just work" -- so if you're producing a "hero" render, Lux Render (or its non-free cronies such as Maxwell and Indigo) are amazing.
