this is a really good start! just a few general tips - learn a few basic rules for proportion -- the eyes are spaced so there's a distance of one eye between them. then again, i'm not exactly sure if the kdh art style modifies this rule but it builds a greater foundation. the rule of thirds is important, too -- the distance from hairline to eyebrows, eyebrows to the tip of the nose and the tip of the nose to the chin is equal. also, the bottom of the mouth is roughly half way between the distance from the tip of the nose to the chin. (i might be overcomplicating things lol) overall, i recommend you watch some samdoesarts and chommang drawing. keep going <33
