Well I'm sorry BZ to rain on your parade.
But I actually still have the first ever Image I used, when making my Overworld. :)
This image clearly shows all the components I used to make my overworld!
The Palette is from my fusion Trainer Sprite.
The hairstyle is from the Rich Boy Overworld.
And the base is based of the FIRERED Overworld.
So Ben. Derp, go away. :)
