So this image of Lurosos here: https://www.furaffinity.net/view/30488056/

What I want to do with the image is have it be as though you're watching this like it's a stream on Twitch. So what I need is a good screen shot from anyone watching a stream with chat on the side.

I would simply use a screenshot from my own computer, BUT, my monitor resolution is 1,366x768 and for my "art" I tend to go with larger images sizes, in fact that aforementioned size is approximately half the size I tend to work with. =O

I don't need a massive 3,440x1,440 I am mostly seeking either a 1,920x1,080 or 2,560x1,440 sized screenshot of Twitch. Obviously having all of your usual task bar icons you use as well as browser tabs while you watch Twitch streams will be nice as well, similar to this image:

So yeah, an image like this:
https://www.dropbox.com/s/pe4bcpt21.....nshot.png?dl=0
where it's not necessarily full screen, still has the taskbar and browser window and all that.

So help with this would be appreciated. =3
