Yes I found the same problem, So a month or two ago I cracked and decided to just get the low res one, double the resolution and manually fix it and add in the detail. Its not 100% (I need to do her hair a lot better) but I added a glow and made it into a destop.
Hi Res Komillia
If anyone wants the image on white or the original file then let me know, I will get around to redoing it so it looks 100% sometime soon.
