Hey there! First of all, I think your over all facial structure is very believable, well done! It's another good thing, that you already identified your own struggle. It is the forehead.. or generally the whole top of the head. Two simple ratios that I'd love to suggest: 1. Rule of thirds: Seeing the underlying structure, I can tell that you already know this concept. Basically you split the face into three somewhat similar sections.. hairline to brows; brows to nose; nose to chin.. Just make sure to not mistake the "Hairline" with the "Top of the head line". I think this caused your struggle with proportion. 2. Splitting the head: Use this to always make sure your eyes are in position. When you split the head down at the middle you'll generally get the height of the eyes. With your eyes already placed you can also use this to determine the top of the head by doubling the distance from chin to eyes. Very useful! I hope this is of some value for you and keep on going!
