Wait. that tree is just getting things sorted out. Why interrupt the process, especially when it actually looks just fine. Take a deep breath, and find something else to do!

Its probably less than ten years old. I would leave it be and let it grow naturally.

Next spring I would cut the two branches on either side of the tallest leader, back to the first crotch. This would encourage the tallest leader to become the dominant trunk and grow taller, faster. The two side branches will become more horizontal and provide a wider, balanced looking tree. Eventually you will want to remove all the lower branches up to these two side branches so you can walk under the tree without hitting your head on a limb.

IMHO nothing to do now.

Agree with both the last two posts. But again, no urgency. A study I once reviewed called into question the practice of removing a whole tier of branches all at once, due to increased chance of decay pockets. But I also know for a fact I've done just that. In any case, elmbelle, if you really feel like drilling down into this, look up the phrase subordination pruning. One good source of such info is the work of an Ed Gilman at U of Florida. If you can absorb what's going on there, your tree knowledge will be above and beyond almost everyone's! But in the meantime, let the thing have all the little food factories (leaves) that it can have. Plenty of time to correct and enhance overall structure.
