Looks about right, I usually nip mine a little bit farther up the main shoot. The way you did it, you'll be fine. In a few days all the little side branches will bush up as the plant tries to figure out which is the main stalk(s) now.
They look great, I've found that you can cut them back even a little more, without actually topping them. From my experience I have found that FIM'ing 2-3 times followed by a topping of what ever shoot is still making it up above the rest(usually the main stem) will turn your plants into wonderful little bushes will minimal effort or skill.
