Roald Dahl's books (any of 'em) and Harry Potter are good resources to study how 3rd person, great voice is done.
I used to prefer writing in 1st person POV, until one day I realized I prefer READING 3rd person POV! So why the heck wasn't I writing in 3rd person?! It was my aha! moment. I had an entire MG adventure manuscript written in 1st person, and I rewrote the thing in 3rd person limited. Man, oh man, did that feel better! The writing seemed more natural, I wasn't loathing myself as much, and I started receiving better feedback in critique sessions.
My advice? Make a list of what you like to read. Do you lean toward one type of narrative POV? Keep on reading! And then, write what you like to read!
