I really love this scan as it is, so I add really simple and discreet things.

I found the link on a fantastic blog of DGM (a french one) :
http://strike-kun.skyrock.com/

and, so, the picture without writings (because I know you don't really speak french, lol) here : http://jumpsq.shueisha.co.jp/contents/train/img/pc_dgrayman.jpg

Enjoy!!!^^
