I don’t know the more involved mutation combinations like the others above do, but for sure your budgie is not cinnamon. In my current signature pic, my ski-jumping sky blue is a cinnamon. Much darker markings than yours, and a slight brownish tint.
It depends on which mutations you want to see in the chicks Keep in mind that if you want blue chicks, either pair him with a blue hen or a green hen that you know for a fact is split for blue or all chicks will be green.
