For real though, use this website if you want to upscale images. It works amazingly well for any non-real life images, but not that well for photos. It even has an option for the output, either JPEG or PNG. Don't forget to choose PNG when you upscale transparent PNGs.
Preferably, link the picture(s) next time. We don't post pics here directly since they slow the thread to a crawl. In addition, next time you're going to want to find a higher-resolution image, since the one you posted was extremely tiny.
In addition, this render was relatively simple, so next time you may wish to look at my Guide to Basic Rendering so you can go without having to waste time waiting for me.
The resolution of that image is too low to add to Goku's profile. I'd be willing to render it for your personal use, but we definitely aren't using it for the profile when we have much higher-res images.
First of all, you're derailing this thread. This thread is not designed for discussion but Render Requests.
