I'm not saying this in a bad way, but I think you look distracted while in goal, like you're scared of making mistakes. Goaltending isnt all about technique,its also about instinct and being in a good state of mind. If you constantly worry about your technique while your playing, you'll most likely make mistakes. You said you needed all the help you can get. I say you should stop thinking like that and just tell yourself you're the best and that you'll stop everything. Confidence is everything. (i'm just speaking out of my own experience, it might be different for other people but in my case, once my confidence was in check, technique came as second nature.)
