Gosh. Fuku-man. You're the third person to plug that wall of mine. XD
And yes, people just don't appreciate a good work when they see one. :D
Neways, you did a great job in fixing up the scan but it does look a little grainy on the top part of the scan.
The night BG is well done though the aurora/shooting star effect could be brighter. The moon reflection looks a little too sharp. Try blurring it out a little.
I'm sure people will overlook those stuff I mentioned because it's the impression of the wall that counts. Details comes later. A fav.
