your problems?
Get a new and larger hardisk and reset your scratchdisk to the new one instead.
As for the wall?
everything is good, until you look to the water and the legs...that kill it...wind over the legs? No, it makes her look
like she is doing Shunpo...and it is weird, cause the water seem like infront of her rather than her into the water.
(you know how you place a tank of water in front of the character? that is what it looks like)
However, the scan is cleaned up real good, clear and pixel free, overall, an okay star background, kinda good, kinda at
the same time trend following like, but it is clear.
I am not too sure why you made the pillars blurry at the sides, but would be better if they are not.
I assume you were trying to give focus to the character, like as if she is moving forward, but it is not too good,
however, overall this wallpaper has showed that you have spent lots of effort over it.
A fav from me.
