I'm still a rookie

It's apparent that I'm still a rookie, because I made a rookie mistake. A friend I hadn't seen in about 12 years emailed me about working on his logo. He is getting married and wanted a couple swing dancing. I asked all the typical questions, and received vague or no answers. Instead of pushing for better answers, I figured I know what he'll like. I came up with a design I thought was perfect. Instead of sending him a copy of the sketch, I just ran with it and did a final version. I sent the finished file to him, a got the reply "It's a great start, but...". After 4 or 5 hours of work, he wanted me to enlarge the hat, add a suit jacket, and completely redesign the pose to have the male throwing the female into the air. I've learned my reason. This time he's getting a pencil sketch.
