The two characters to be drawn are named Gustav and Irina. They are the protagonist and the antagonist in The Essence of Villainy, a story of mine(you can google it). Gustav is a villain, Irina is a heroine. They both have individual characteristics to them, but the most important thing I wish from the art is that it isn't too terribly exaggerated(think Steven Universe). If someone can draw manga, that'd be cool, but I'm taking some other ideas if you can show artwork references.
And the area I need drawn would be a long, dark field of grass with a looming forest in the back(and that forest is on fire). If you can fit a castle behind the villain protagonist's back, that would be great... but it's highly unnecessary and sounds like an artistic impossibility, too.
And thank you for your time.
