I kind of prefer the 1st version, mostly because it's more colorful. I would suggest to make the upper portion of
the sky less green and more blue, though. Green somehow looks a bit...unnatural for the sky. Unless she is on Namek,
lol. And yeah, there are some sparkle issues in both versions - in the day version, one of those sparkly things is cut
off in half (the left side of her hood where the flowers are) while in the night version, the same happened to the
sparkles in the very middle of the wallpaper. I would also suggest to keep the grain on her clothes only since things
like skin, eyes and hair are all usually soft so grain makes them look oddly scratchy, like sandpaper.
And of course, you can upload both versions; all you have to do is decide which one you want as the main, thumbnail one.
