Bungees are way too long. The cylinders should be up about 4 inches on the top. Those are practically dragging. This is common with some SM divers I've worked with who were trained by less than qualified instructors. It usually takes about 10 minutes in the pool to see if the instructor knew what they were doing. I've often stopped someone as soon as they went under and pulled the bungees up 3-4 inches and they are amazed at the difference. Your chest should be the lowest part. Unless one is really skinny the chest should be an inch below the level of the cylinders. The cylinders in this photo are not in trim. If you were in trim they would be cocked at about a 20 - 30 degree angle. They should be along the line of your body.
