In what resolution do you want it to be?
One resolution there is 1280x720 and the other is 1920x1080(HD).
I use Photoshop so I can tell you how to upscale in it, I have no idea about other graphic editors.

I can make it for but it will take some time. I have many works going on. You have to upscale every image in the asset to your resolution. You can also watch any tutorial (on YouTube or Website) on how to upscale images depending on your graphics editor.
Or simply just wait I will make it for you as soon as possible.;)
