Good advise here, If you have a big yard or a place to shoot you can't get enough practice from a blind. Estimating yardage can be a challange at times. I keep a 15 yard piece of mason line in the pack and use it to put the turkey decoy out each time. This will help when you get birds coming in from behind you, I have shot over the backs of some birds that I thought were farther then they were. Instead of your camo use a black sweatshirt and black face mask (silk works good) if you open the blind up wide,this will help cover some of your movements.
