Welcome to section 1!
The first thing I'd like you to be aware of is the numerous changes in meter. It can be very easy to forget about these things while you're learning a new piece so try to keep it at the forefront of your mind if you can.
OK, the first three bars shouldn't present too many technical challenges for you. However, when we get to bar 4, things start hotting up in the technique department!
With this first arpeggio pattern, I find it best to focus on the repeating shapes occuring on the 4th and 3rd strings and the 2nd and 1st strings. In the 5th bar be sure to be as accurate as possible with the position shift and keep your practice tempo nice and slow so that you maintain complete control over everything.
Bar 6 requires some awkward stretches with the left hand and I find it is a good idea to practice this part on its own concentrating on accurate positioning of the index finger. I usually find that once the index finger is in place correctly, everything else falls into place nicely.
Tread carefully in bar 8 as you'll find that the opening note of the bar is not the root of the arpeggio as before. This may throw you initially so again, slow practice is the order of the day here.
For bars 10 and 11 you'll have to draw upon your alternate picking skills to make the best of this passage. Be mindful of the triplets that occur throughout this part. Once you have the basic rhythm down try to concentrate on the phrase as a whole rather than individual notes as it will help you to achieve the desired result.
