The same principals apply to the second section as we discussed in the first section. During the rising and descending octaves section, it would be worth really emphasizing the dynamic element to achieve a positive effect. A simple rule of thumb for this kind of piece is to increase volume as you ascend and decrease the volume descending. Only use this as an initial guide though because it can become very predictable if you overuse that formula. During the final cadences, don't be afraid to go overboard with the dynamics as it really helps to hammer it home to the listener.
OK, best of luck and I look forward to hearing and seeing you performances over in the forums!
