This is more of a nitpick pet peeve of mines that I used to have but learned to accept, but it's when the artist fuses the middle and ring finger together. I've been told that's how the hands naturally rests and can see that but it I appreciate when the artists take the time to show the subtlety and separate the two.

Pic rel: I went on art station and saved the first example I could find, no offense to the artist ofc.
