Unnecessary to frame vertically around windows?

[Lindgrenski]

Currently decorating an attic room and have just replaced the window. The wall is constructed as follows:
Old plank wall
Vertical 145+45
Plastic
Horizontal 45
Horizontal OSB
Vertical gypsum

My question is whether I should have skipped framing around the entire window and instead let the last layer of insulation go all the way to the vertical studs to break the thermal bridge there.
The vertical pieces don't seem so necessary since they don't exist anywhere else.

I think it looks good, you won't save any noticeable money by removing the studs since the only real thermal bridge is the frame.

You need to have something to screw the discs into, so you did it completely right.

You need something to screw the discs into, so what you've done is entirely correct.

I have nothing in the corners except for the horizontal battens, so for that reason, I don't feel I need them vertical. But I chose to keep them anyway, mostly because they are nailed and too cumbersome to remove.
