I wouldnt worry too much about the horse steping over the jump. That is probably the most natural thing to it, with a small jump. Some horses no mater how much impulsion will still just step over it. If you could choose between steping over something and jumping it you'd probably choose steping.
Your 2-point looks good, I like how your not too far out of the saddle. You are a little early but like the others say that is ok because you don't need to worry about refusals and stuff at this point. The only thing I think you need to work on is keeping those heels down.
You have an amasing foundation and look very impressive for your second time jumping!
