I think the logo should have the same look and feel as the default intro video.
I think some of the newly approved themes need to be added
I like the neon text. So maybe a few more instances of that calling out top features.
Just some ideas...Looks great, if you add more themes/layouts I would shorten the display of them as a quick 30 seconds.
10 themes, 30 seconds each, 5 minutes total, 10 callouts with neon text.
Thats all I got....
