Not bad. As a Flash designer, I've always wondered what LiveSwif was like, and found this tutorial searching for examples of what the interface looked like.
Given that this looks like it was made in LiveSwif itself, it's not bad. Thankfully you made it look a lot more professional than some tutorials I've seen, and it looks like you put care into avoiding typos and making the instructions fairly high-quality.
So what needs improvement? First off, the background is pure white. All games I've seen made in LiveSwif feature this, not sure if it's something you're stuck with but it's annoying. You could have at least added a square on a lower layer to make a colored background. But white is a little too bright for me.
Second, the images you put in are a little low quality. Flash automatically compresses images you put in, but allows you to change them back to full quality. Not positive, but my guess is LiveSwif allows this too. It would have made text much more legible. In fact, having the interface of the program as a giant background would have been really nice.
Third, some things that should be explained aren't. For instance, the two trash cans, one of which you insist is better to use than the other. Why? What's the other one do? This is a tutorial, you're supposed to explain this kind of stuff.
Last, the tutorial could use a lot more interactivity. You call this the LiveSwif tutorial but only cover preloaders and buttons. Perhaps a tutorial that has an extensive branching menu would have been better; allow players to click through only the features they need help working on so they can get their help easily.
