[Diaries - Beginner] 2D Design Sheets Are Misleading (Kinda) (Patreon)

Hi guys, it's been a while since I write my previous diary. In this diary, I'm going to explain the usage of design sheets as a reference and how it is often a bad idea to be heavily reliant on them when creating a 3D character.

When I work on several 3D models, I usually try to find the design sheet of the character to make my work easier. VTuber members from a well-respected agency often have a complete design sheet from all angles. However, I have to admit that most of the design sheets that I have are always mutually exclusive between one perspective and another. Essentially, most of the design sheet that was created is not proportional to the front view. 

One of the most noticeable problems with these design sheets is that the nose-mouth length in the side view is too long. When you try to combine the front view design and the side view design, the shape of the face is going to be triangular when you try to see it from the top. It gives this "Habsburg Jaw" vibes into it and I really do not like it.

So, how can we mitigate this? We can actually try pulling the cheeks forward to make the face rounder. However, when taking a look at the face from a 45-degree angle - Z axis, this resulted in the outer shape of the face coming out of proportion and making the character look like from the 90's anime. Yet still, when you take a look at the model from the top view, it still has the Habsburg Jawlines.

The best solution that I can find is that by reducing the length of the nose-mouth area by half of its length, the model can become a lot more proportional. This means that when you take a look at the model from all angles, the model looks quite round and enjoyable to look at. If the problem still persists, you can try to reduce it even more, rotate the nose-mouth vertices at a suitable angle, or increase the cheek size.
