This lick is another that utilizes a couple arpeggios within C Lydian to accentuate various tensions.
The first arpeggio is a Cmaj9, which is comprised of scale degrees 1 - 3 - 5 - 7 - 9
Obviously this arpeggio is outlining the tonic chord, which is never a bad choice.
The second arpeggio is a Bm7 arpeggio, which is comprised of scale degrees 7 - 9 - #11 - 13.
The lick ends with a chromatic descension from A to F# (6 to #4) which really stresses the Lydian sound.
