Here is another guitar lick in Drop D tuning. This one is a little faster than the last two but shouldn't be too hard with a little bit of practice. The bulk of the guitar lick is played with a 16th note rhythm. Try to make the pull-offs smooth and practice the chromatic descending part in the last bar to make it the same speed as the open string part. Try different degrees of palm muting to alter the intensity of the open string parts. Try repeating the guitar lick a few times and work on building intensity as it progresses. Again if you have a drum machine or drum pattern that matches try to play along. Ok here is the guitar tab:
