RTF is a global modification that replaces all towns in the game.

You need to apply a "green mirror" effect to the metal!

Of course! But since I haven't even started painting yet, the final result might be very different because I don't have a clear picture in my head of how the units should look, and I haven't come up with the color schemes yet.

Looks like the Nagas from Warcraft.

Oh, I need to see how the Nagas were painted in Warcraft.

I didn't find anything useful in Warcraft, I'll try using the color of the Blood Naga... but first, I need to try to combine the turtle details and the armor on one texture.
