The whole animation is very sleek, bright and eye catching but there are a few things that I think could improve it.
Firstly, I think the preloader would look better with an easier to read font, like a Windows default Verdana or something of the sort. Or, better yet, get rid of the "Loading...50%" text entirely and let the boxes do the work.
I think the "Only Way Is To the Sky..." text should be readable as soon as it appears, i.e. without the blur, it made my eyes go a little funny.
The professional businessman is a good choice to give a professional feel, but he does look a little out of place. Maybe try softening the edges of the cutout or something?
