Well, it looked pretty good here, so it should only improve with more practice!
The black bars that you added didn't cover the entire top and bottom of the screen: you can see white and some sprites above and below them.
I don't know what happened there. The black bands I cut to the exact size of the document, so it must have stretched when I uploaded it. Thank you though, I'll ensure it won't happen next time.
Really nice job! I suggest getting a dropbox folder and synctoy to always have a backup file in the cloud. Saved my ass for a presentation once :)
