This is a solid start, my man, but I want you to try to keep it one finger per fret. You're in the second position, which means that your index finger should play any note on the second fret, your middle finger anything on the third, ring finger on the fourth, and go ahead and feel the burn on that fuckin pinky on the 5th fret.
If you're having issues stretching your fingers apart that far, go ahead and check out this little video I did for folks with short fingers, like me.
