From that photo your fit looks pretty good, but you look a bit uncomfortable and stiff, as if you want to be more upright. I'd raise your stem a bit (a couple cm?) by however you want to do it, and gradually lower it a few mm a month or something, until you have comfortably arrived at a more optimum position.

Or just keep a more upright position. There's nothing wrong with it, except you'll be fighting the wind more, and it puts more of your weight on your rear and less on your hands.

One thing I do notice is your saddle position looks quite high, but I can't see your knee bend that well obviously since it's on the other side. Also, I'm from an era when a much lower saddle position was used. Still, I would try lowering it a bit. It may improve your comfort level.
