Well, personally, I do like the tower. I find it very elegant. Please people, remember that what you're looking for are 2D renderings, try to imagine the tower as if you were on La Défense esplanade.
Clearly, I'm no fan of the hairs on the top of the structure. The pinacle has to be rethought. However, the tower is well-proportionated and I don't find the design awful at all. It's actually very pleasing. The only thing I'm scared is that the tower could look fat from some angles, but once comparing the floor area to the height, we do realize it couldn't be the case. Seriously, this will be a great addition to Paris.
