Look at the bottom of the finger you drew orange. That's supposed to be the pinky so there should be no skin behind it like the line suggests there is.
I'm bad at explaining, but essentially the diagonal line at the bottom should connect to horizontal line at the bottom in order to look correct.
In it's current state, there are only 5 fingers shown. That's a fact. However the drawing line being drawn weird suggests that there is a 6th finger blocked by the others preventing us from seeing it.
At the end of the day though, I might just be insane because I've seen way too many incorrectly drawn hands in Korean and Chinese works. It just kinda happens often cause they stick to a weekly upload schedule which rushes their art sometimes.
