I don't know what the reason for deletion was, but I'm guessing it was the low quality of the image,
especially when it comes to lines because they look very jagged in most places. I see you made most of them look better
in the second revision but some of them still stand out. Have you considered vectoring the image? Or finding a better
quality one? Though, that may seem hard if you used a manga panel/image to create the wall.
Right now it does look a bit better but it also looks a bit....plain. Maybe some colors would refresh the image?
I'd also suggest to flip the image since most users have their icons on the left side and the girl IS the main
focus of the wall. Also, it would be better if you vectored the image, too. And definitely add some colors to spice it
up a bit.
Just my two cents. Keep it up!
