help.... plaster around window frame

[Johntheboy]

Hi,

I've had my plasterer come and price up for some work in my living room and he's due to start this week. However I've ripped down some timber work which was effectively just a curtain pole blocking out loads of light and I've got a strange set up around the top of my window now.

Just wondering if this will be easy for the plasterer to get around, I've attached some photos and a section sketch of what it is now and what I think it would need to be, if anyone can tell me if I'm on the right lines or if this is an easy fix that would be great!

Looks straight forward enough, a little fiddly but nothing that either an angle bead or stop bead cannot tidy up.
