you did a fairly good job for only folding the pages, however, it is common for people to remove the pages completely while scanning to avoid this issue of distorted, or tilted images.
If you are not comfortable destroying your manga for the sake of sharing it, then we are all very sympathetic, and understand that you did as good as you possibly could to scan the images. That being said, certain measures can be taken to doctor the images, such as Photoshop, or maybe a simple correction with a windows photo editor could help, since translation for manga scanned in such fashion can be difficult.

It's alright I guess, but you may want to remove the "language:english" tag, as there isn't a word of english anywhere in it, with the exception of the first page for about 5-6 words.
