You ask if you are ready. What does your coach say? Hard to say without having seen you skate, but in general people would have first worked on full-rotation jumps like loop or flip where you rotate around your right side (assuming you are a CCW jumper). In a waltz jump you rotate around your left side. Also unless you're quite strong you'd need to be crossing your legs for an Axel, again a waltz jump would be open whereas on a flip or loop, especially a loop, you'd be getting used to crossing your legs and then kicking out.
As granita says, landing a waltz jump into a backspin will help - I think you must make sure you don't travel but start spinning as you come down. That basically is your Axel jump once you stay in the air for the backspin.
Personally I wouldn't take advice from people on the internet who had never seen me skate on something like an Axel unless I already had a very good idea of the mechanics of the jump and how that related to way I was doing it.
