Yep, I agree 100%.
Viewers are clearly aware that Vanessa is sitting in front of a large screen due to the sport cross.
Why not, at least for the start of the bulletin, closer, and throw to ads, zoom the image out a bit so that we can see a little bit of the set away from the TV, as you say, just like is done in sport.
It would be easy to achieve now without needing to do anything major.
One other minor thing I’d like to see is a change to Vanessa’s script at the start. The way she goes from “Good evening.” straight into a story seems off and a little cold, especially when there’s no opening headlines.
It needs to be something a bit more inviting like “Good evening, thanks for joining us. Firstly tonight, …”, just to make it a bit more friendly!
