How to make vanilla textures(from somebody also totally having no idea how to make better textures)
Try to make only 16x16 textures(vanilla texture resolution), and
(1) Classic(programmer art) textures: Do not make them look smooth(aka "antialiased")
(2) Modern(1.14+) textures: Smooth some(but not too many or too much) edges.
Coloring: try to download vanilla textures and use color picker to get the colors, and try not to make bright and different colored lines/patches next to each other(e.g. sky blue with bright pink). Unless making a very bright block, try not to use too bright colors at all.
Shaping: try to study vanilla textures and their shapes. MCreator's default templates can help you A LOT.
