Arpeggio Picking Exercise

This is a guitar lick that works as a great picking exercise. To play along my guitar is tuned down a half step. It is based on arpeggio shapes using a transition from E minor  to F major. Use alternate picking to keep the overtones from ringing when using distortion. I start on an upstroke. For a real challenge you can try strict alternate picking. I find on this lick though a bit of mini sweep picking or economy picking if you prefer - helps increase the speed and fluidity.
Here is the guitar tab. Cheers.
