Another useful thing to keep in mind is the fingering you use for your fretting hand. Notice that your index finger did not move from its location and stays anchored to a fret for the majority of these scales. Whenever your solos are in the same location on the fretboard, you should try to keep the same fingers over certain frets. For example: If most of your solo is between the 5th and 8th fret, anchor your index finger on the 5th fret, middle finger on 6, etc. This will make you a little faster in those ripping solos.
It is a good idea to work with a metronome on these to keep a steady pace going. Once you sound good at one speed move it up a little faster. Keep increasing the speed and pushing yourself. Have fun.
