Looks good with the dark tone. I think the dimensions are a bit off in that rendering, as it will be as the towers on left. Another note is how horrible photos they sometimes use to plant renders in. That looks like taken with someone's cell phone...
This location could also take a taller tower, as the position to the park makes it a landmark building that should really stand out. Very nice addition, nonetheless and that area is getting denser with the other tower going up in the corner to the left.
