Anvil, Lol
Alright so I'm planning on making this a decently long review since your submission has quite a few points(good and bad!) to discuss.
For music you had a pretty nice selection, nothing that greatly matched the tutorial(except maybe the first song) but nothing that took away from it either, and the ability to stop and play the music was a great addition.
As for the graphics they were simple but not bad, however there were a few parts where your graphics really took away from the experience by making things hard to see and read. (especially when you wrote words instead of using a text tool). So, as a whole I'd say decent graphics but they really can(and should) be improved, at least dealing with things such as text and menu navigation.
Speaking of navigation is was quite difficult at times. I like where you were going with having the clouds signify the click area to see that particular tutorial, but at first glance the entire page looks like less of a menu and more of a...well I don't know. It was confusing for a moment. So maybe next time order it in a way to let them know "Hey! I'm at a menu page!" Maybe by enclosing the text under each picture(such as the Clouds and Rain) in a styled button just to let people know it's indeed a button instead of a pretty picture. Also as I said above it was quite hard to read the Motion Tweening text the way your wrote it, so maybe do that in a clearer way. Other than that though the graphics were simple yet great for the purpose and I especially liked your cloud tutorial(I am horrible at Clouds and the ones you produced were very nice actually) And they also blended well with the humor you used (Which is a great point in this tutorial, too many are like talking to robots, with yours it is more human and comfortable, so it really holds interest) I especially liked the humor though (Anvil lol)
Alright, now to the tutorial contents. This was an informative tutorial but there were a few things that need to be improved upon. First off is the way you wrote. It did add the comfortable human element which so many others seem to miss, but you also wrote in ways that were sometimes confusing, even to people with beforehand flash knowledge. Try writing something and then reading back over it, correcting and typos/mistakes and put it in an easier format to understand. While you read it ask yourself "If I am new to flash will I know what this means to do? Or understand what this can do?, Does this sentence make sense?" Also I might make the simple suggestion of putting the actionscript you do post in red so as to make it more noticeable against the over-all text.
Finally while I don't agree with posting to another's tutorial(on the basis that people will go to this tutorial expecting the basics, but then learn it requires knowledge of a specific nature before hand) I will say for your case it wasn't such a horrible decision since you were worried about stealing someone elses work. But if you must link to a page, why not make a button they can click instead of a link they must copy&paste, it would make them more inclined to actually click it and see)
Well that pretty much wraps up my review. Over-all this was a pretty good and imformative flash, but it needs some work to be a great one. However I see a lot of potential in it and hope to see another one in the future.
