Keep it fun, like Bear heart said..."It`s supposed to be fun".
One thing no one else mentioned is you must have good arrow flight for consistency. Just like with a compound, good flying arrows are a necessity.
All the advice you can get is good, but in the end, your are going to develop a style that is all your own. Maybe made up of different things you have learned or seen others do. Maybe all your own.
Too much draw weight is probably the biggest culprit in regards to slowing down the progress of new traditional shooters. Drawing your bow should be no more difficult than walking. Too much weight at the start prevents you from finding a consistent, comfortable anchor point.
Once you find an anchor point you prefer, it will probably stay with you for life. Shoot a light bow at the start to find this preferred anchor.
The twenty yards and beyond you are used to with your compound, has changed to twenty and in. I can stand and shoot along side anyone with a traditional bow, and hold my own. I practice out to, and beyond thirty five yards, but for hunting, my realistic, effective range is around twenty yards. "Realistic" means, I can pick up my bow and make my FIRST shot land where I want. Any time I want.
Keep it fun...don`t turn it into "work".
And remember, the next time you shoot at the bottom of a five gallon bucket, don`t shoot at the whole bottom of the bucket...shoot at the tiny little knob that is molded into the center of the bucket. "Aim small...miss small".
