Hi iJunaid
It's great you like this theme and yes I could resize it, but that would be too easy for you and then what would you do next time you want a theme resized? Why don't you try resizing it yourself? I did post a
1920x1080 background image which you could use as a starting point. I put together the
resizing guide to help with such a question.
Have a go and if you get stuck then let me know and I'll see if I can help point you in the right direction
