Rate me as a pitcher?

alright im in 8th grade. i have great command of my fastball. through 5 innings im sitting at 67mph but ive reached back and touched 71-72mph a few times. my slider has an average break of 13 inches, which i could get up to the whole plate if thrown a little slower, but i keep it between 55 and 60mph. I can manipulate my curve to go 12-6 or start behind the batter and break across and down. i throw it about 50mph. my change is ok, good arm speed and down and away movement. my knuckleball is also ok, i struggle controlling it once in awhile.
