When it comes to bringing it to life, I like to design according to the render and its characteristics, adding more of personification, as when it comes to Leonidas and Sparta, its a bit known for their mess. And overlaying it would add more contrast to it, and since there has been much lightening and brushing some areas would shine out more than others and the colors would have a bad imbalance, and lowering the opacity, it would look good if its around 5-20%, so on point.
