Hmmm...
I liked the idea behind this entry, but can't say I really agree with everything you say in it. Splitting up the awarding of stars for example. I like to think of myself as a fair reviewer, and marking someone down for no preloader or slightly dodgy sound when everything else about their entry is damn near perfect just doesn't seem fair somehow.
There is some sloppy spelling mistakes in this entry, and from the way that you phrase some sentences, it is clear that English isn't your first language. Still, a spell check is a must before submitting something like this which is mainly composed of words.
Also, your file size is fairly excessive for something which is essentially a tutorial which is mainly text. Whilst the music was great, it that is what was taking up most of the file size you should have found something smaller to keep the file size down for the users on a dial up connection. Especially since this is a tutorial and most people would be annoyed if they waited a good 5-10 minutes for a movie to load and it being because of the music...
