Bubble doesn't look consistent as it seems to imply some origin the bubble goes from, which doesn't exist. Just bell in circle would be fine, as for me.

Another thing is that prompt window design is linked to all styles but it can be inconsistent with some (f.e. dark or game dedicated ones and so on). Probably it will make sense to move it to prosilver only.
