There's a bunch of great upscaling filters. I made this using the gimp (G'MIC's difussion upscale and thin brush smoothing, and then film grain). But waifu2x is even clearer at upscaling than diffusion. Wish they ported it to a gimp filter.
Sure, you lose some detail, but it doesn't need to look bad. This looks proper.
