learn the natural minor scale (aeolian scale) and then use that instead of Minor Pentatonic. that's a start.
Diatonic scales.

Ionian (major)- 1 2 3 4 5 6 7
Dorian- 1 2 b3 4 5 6 7
Phrygian- 1 b2 b3 4 5 b6 b7
Lydian- 1 2 3 #4 5 6 7
Myxolydian- 1 2 3 4 5 6 b7
Aeolian (minor)- 1 2 b3 4 5 b6 b7
Locrian- 1 b2 b3 4 b5 b6 b7

In the key of C Major, they would all include the notes C D E F G A B, the order depending on which mode you are playing in. , Major would start on C, Dorian on D, Phrygian on E and so on. Which mode you are playing in is not determined by the root note, but the backing chords. If you play a C major chord, if you play in a position of Phrygian, it will sound just like C Major because they have the exact same notes. However, if you would play an E Minor chord under it, the Phrygian feel would come out.
