Haha yeah that second picture looks a bunch better. At this point, I think you have three adjustments you could potentially make, but both are contingent on your personal comfort:
1. Your seat may be just a TAD high, but if you're comfortable and powerful there, just leave it.
2. Now you may be a TAD squished in the front end! (This is the opposite problem from before). However, this one is easy to diagnose. If, on your long rides (90 minutes or more) you have *any* shoulder or arm pain (particularly in the triceps) I'd look to get your aerobars forward just a bit. But if you're totally comfortable, then great!
3. If you can get "lower" in the front end (with a more negative stem of the same length), that may help your overall speed, but at the same time you may not be as comfortable, particularly in your neck and back. If you're only doing sprints and olympic distances, though, it may be worth it to try and find a lower stem.
Again, these are simply "personal preference" adjustments but this is a much better position.
