Hi @emmawalt, thank you very much for your participation!

You are right, drawing hands is quite a difficult challenge.
I have seen other drawings of yours and when comparing them with this one that you show us, I cannot avoid telling you that you have made a very lazy attempt.
You drew some helplines and some divisions to guide you but you didn't consider that these should be correct. The thumb, for example, is completely disproportionate both in size and in its division. The position of the knuckles is almost imperceptible and the thickness of the fingers does not correspond to their location. What sense does it make to make lines as basis help?
