Coming from someone who has no experience in character design, I find the MetaHuman Creator to be interesting but somewhat lacking in certain areas. The more obvious and known ones are lack of assets such as hair.
Now to more personal things, first off, I think that when creating characters, you should be able to choose eyelids and white eyelids should be more defined. Most white characters I end up creating tend to appear asian. This problem doesn’t seem to occur as much with black characters.
Next, I think there should be more options in terms of adjusting bone structure, more specifically the jaw. The cheekbones have a pretty good range, but the jaw doesn’t.
Third, I think it would be great to have a body fat option. Most of the presets range around 15-20% body fat but I would like that range to be increase or adjustable.
Lastly, I think certain things such as body proportions should have more customizability.
