I really didn't know what I was doing, so don't ask me about the content lol.
Every comments and suggestions are welcome, but from tomorrow to this weekend, I won't be here, so I'm sorry if I can't respond or fix this image.
So many things I did with this image, so undoubtedly, I had mistakes.
Please view in Hi-Res because the quality is reduced considerably in the normal resolution.
