OMFG U ARE BLAM BA1T! (Kidding)
Seriously, it's good that you created such a tutorial. There are a lot of idiots out there who don't know anything about writing reviews. This has even improved my own writing... Let me try what I learned here.
Audio - Pretty nice techno song (You couldn't use mine?) that seems to fit in with the NG atmosphere. You didn't just use the "Endless Handbag Loop" that I see so often in this type of tutorial
Animation - None here. A transition between pages would be nice, for instance having the entire page move left instead of just going there.
Graphics - Good. Your screenshot quality could be better. Also, nice use of the TF2 font.
Overall - Very good! I would like to see some other flashes explaining some other things you would like to see people do better on. Thank you and have a happy Spore Day.
