As always there are no curves in your mocks - the rostrum isn't circular, it's an 18 sided shape, and it shows. Also, I find the presence of three screens that seem to be floating on the side of the wall a bit odd, and really it just doesn't look up to the new higher* standards of studio mocks on this forum.
The dimensions are vague (I've never heard anything about the size of Newsline's studio and wouldn't initially think it's the same size as Scotland's), the render is non-existant, and it doesn't look like it's had the time or effort poured into it that dg6's mock benefits from.
And as for the lights...
