New default characters are inaccurate

An entire cast of new default characters, and an updated Alex & Steve have been introduced in this beta. However, they're made with the character creator, even though they were all based on skins. This causes a bunch of visual issues and mismatches, some more severe than others.

Common issues within all of them:

• Less saturated skin and hair;
• Loss of skin detail, mainly around the forehead;
• Inconsistent contrast between different shades of the same color.

Character specific issues:

• Alex: Doesn't match the updated Java Edition design in the skin details, pants and boots, skin color is too light.
• Noor: Skin tone is too grayish, eyes aren't dark enough;
• Ari: Skin tone looks sunburnt;
• Sunny: Skin tone is too dark and reddish ("Medium light - Deep" skin tone would be more accurate);
• Makena: Skin tone is bordering gray, mouth is reddish;
• Efe: Mostly the common general issues;
• Zuri: Most severe case of loss of skin detail, brighter skin shades are desaturated and have too little contrast.
• Kai: Mostly the common general issues;
• Steve: Doesn't match the updated Java Edition design at all.
