Ok, varsogod, eccoli, and all that.
These are both about 3000 x 3000 (three times original size).
The first one is here.
The second one is here and has a "sharpen" filter applied to it. It makes it less blurry-looking, but different. I suppose it's a matter of aesthetic taste which one every person will prefer.
I think both are free of pure white pixels.
They are all also slightly richer in color than the original. I thought this was an improvement and probably closer to the original artwork, but if you prefer, I can re-do it with the original's lightness.
