Even more sixteenth notes. YEAH! The challenge here will be making sure your hands stay in sync, especially on those descending lines. The cross-picking is nothing too crazy, but the faster you go, the harder it gets. Make sure you are practicing at a speed that is comfortable and attempting speeds you can handle. It will do you no good to try and play faster than your mind or hands can move. So play for cleanliness, and increase your speed slowly.
