I just thought I'd post a separate topic for this, rather than having anything related to it on the MB3 Spoiler thread.
(Though I did mark this spoilers, just in case)
I haven't found any typos in it thus far, but I do have one suggestion about the God Metals: Perhaps the position of the Atium/Larasium symbol should be switched? If Larasium's alloys provide expanded Physical and Enhancement effects, shouldn't it's symbol be below that half of the chart (I'm talking about the symbol next to the "Mistborn" text at the bottom). I think that would make it more intuitive if the atium and larasium were switched like that.
Another thing on the atium/Larasium descriptions: "Larasium", in the description, is capitalized, whereas no other metal's name is capitalized. It just seems slightly inconsistent to me, but then again Larasium is pretty special.
And perhaps on the tin description, instead of "All must be increased at the same time", it could be "All will be increased at the same time." The way it's phrased now, it sounds like the Allomancer needs to work to increase all of the senses at the same time, whereas in reality he or she doesn't really have a choice in the matter.
Finally, on the Key for External and Internal Metals, it isn't exactly clear on first glance that the text "Internal Metals" is referring to the inner circle there.
In addition, I hope a wallpaper of 1400x900 is one of those "standard sizes"
