Nearly 30 years ago I was going to a U3A painting group. Some of the members were men who had been given expensive sets of paints as retirement presents, but had never done any painting before. I remember one in particular who was producing some lovely little paintings with a rather dreamlike quality. He was very unhappy because he couldn't make them look like the pictures in the instruction books, however hard I tried to convince him that his own vision was far better than just reproducing someone else's. So I would just say that if you are starting out don't get too hung up on the step by step instructions or the How To Do It videos. Your own vision is just as authentic.
