Ehm, save as PNG.
It will be confusing for people who have never played TPT. Also, make pictures, or add ~ before save id at least, cause I'm tired copying id into TPT -_-
I'm not that great at art but I am giving people a few ideas:
-Maybe make famous logos such as Mario or Minecraft out of art and say something like "Make Use of the Amazing Elements in The Powder Toy to make your Favorite logos"
-Make sign saying The Powder Toy out of normal things such as COAL or IRON and have the same one but with the deco layer on it and have a caption "Decorate your Work with the Amazing Deco Layer"

Bad ideas. TPT's main feature isn't a decoration layer. Even recommendations at first post say you not to use deco a lot.
Cool, but you could add more things related to TPT. All these flags are kinda useless, and don't show how cool this game is.
No, that's just a collection of art.
I'm thinking of having a go at this, but whatever I do isn't going to be very good xD
