hand practice sketch

I forgot when did i draw this hand practice sketches but one thing is for sure that for me hands is one of the hardest part for me to sketch. Im into portrait but i never sketch a whole anatomy and thats my bad. And so i did this hand practice out of nowhere and as a person who is actually bad at sketching hands i found that my hand practice sketch is not that bad which is actually the opposite of what im really expecting. Maybe i just need more practice something like that.
