NHF – new heroes for Heroes V 3.1.

Of course, black looks better, but I think it would be better to make the shield and muzzle in the colors of the lizard's skin! Like a kind of camouflage!

Well, I disagree here - in that case, the detail will suffer, and the drawing won't be as visible because everything will merge into a single-color spot - if possible, the details should be of different colors, while also being complementary and contrasting (a rough example - black/white - the colors complement each other and contrast without merging into one absurd spot).
By the way, I drew Iris about a month ago - what do you think of this version?
