Welcome to TradGang, Wayne. You seem to be enjoying yourself, although the dog seem less than impressed with your shooting. You appear to have a bow weight that works well for you, so that you can draw and shoot with very little stress. I assume you've done some sort of test to determine that you're left eye dominant? I see a little overgripping with your bow hand. You might want to try gripping with just your thumb and forefinger, with the other 3 fingertips just lightly touching the back of the bow. The weight of the bow should be against the meaty part of your hand between your thumb and lifeline. Your knuckles should not be parallel with the bow handle, but more like a 45* angle to the handle. Hold the bow just tightly enough so you don't drop it when you shoot.
I can't really tell, but I wonder if you're torquing the string with your string hand. The natural inclination for a LH shooter is to put a clockwise torque on the string. If you place your hand on the string so that it is twisted in a slight counterclockwise direction such that your fingertips are pointing slightly up, and try to maintain this orientation as you draw the bow, it helps prevent torquing of the string. Keeping your string hand as relaxed as possible helps also.
You seem to have an open stance, which means that you have to rotate your shoulders into alignment with the target as you draw the bow. This is a good strong position, but you just have to be sure that you fully rotate your shoulders into alignment with the target, rather than remaining open at full draw.
Some of this is just guesswork, so take it with a grain of salt.
