I have drawn for years and not a day goes by where I don’t reference real pictures for hand positioning. Hands are hell to draw and I don’t think there’s a perfect method to them, so references are the best option (at least for me). Maybe try some hand studies where you just look up a lot of hand pictures and try to draw them to get a feel for how hands look in different positions and angles.
Referencing doesn’t make you any less of a skilled artist, in fact it’s very wise to actually use references when you are unsure about how a hand should look in the position it’s meant to be in. I hope this helps a little, and good luck with your hand drawing journey lol, keep practicing!
