Im studying arts, and I know from experience that all the theory shit doesnt do anything, you need to experiment, retry, edit and spend long time on drawing, female bodies arent hard at all, dont look at stupid puppets, you need to see the real body, even if its might not too normal, but nude people are very inspiring and are very fun to draw! Just keep on trying, dont give up, I currently have to draw photographical, once I took a paper of someone and I tought something would fall of, and it was a drawing xd. Gl!
