hey guys i want to know if this is the right angle(parallel) :
Pretty much, it should be flush with the guitar body.
Agreem it's good. Slightly confusing for me though with those fine adjusters at the back with an angle. Always hard for me to see it right first time, but it should be like this. If you're not sure if it's flush you could try laying a ruler flat on the body and see how far it sticks out/differs above/below it, usually works for me quite well instead of comparing it to the body.
