Good listening. You "power up"and then try to hold a powerful delivery. So focused on the technique that you aren't present in the work and we miss your personality. Prepare, of course, but don't forget to allow YOU to be in the performance. As if saying it to someone you'd like to help, live and connected with that one person. A very difficult thing to do at first. The practice is important; imagine someone to say it TO, or some actors put up a picture to speak to at their work station so they can drop into that realism easier, and delivering their performance to someone. It can be a pic/imagining of anyone you think you COULD talk TO. Keep going.
