you're probably hitting the wrong strings cause when you alternate pick, your pick goes too far away from the string after you hit it. you only need to hit it hard enough to make a sound, no need to smash the strings. and your hands are probably going slow or hitting the wrong string cause your fingers are too tense. just slow down a little bit and lighten up how much pressure you're putting on that string. you only need to put enough pressure on the string to make a sound, and ive found out its not that much pressure.

my advice is, ( please just try it and see if it works for you, dont ignore it)

1. put only enough pressure on the fret board as to make a sound. this is usually a gentle touch, depending on your string action.

2. your picking hand and your pick itself are very important. i recommend trying heavy picks, and if you have a small hand get a small heavy pick. they allow more control than those soft picks. secondly, try to pick the strings using your wrist, not your elbow. the wrist is less tiring anyway. third, try to pick the string at an angle with the pick, not straight flat. okay now fourth, try to apply only as much pressure as needed to make the string sound.

3. USE A METRONOME. IF YOU CAN'T GET ONE, GO HERE!

combine all of these together and you'll play alot better and practice the chromatic string picking excercises with it and your hands will be in sync.


now, theres one last thing ive got to tell you. playing great guitar doesnt come overnight. you have to practice ALOT. and i really mean alot.
