I usually wall only series I have seen/read or know something about, that way... I know the overall mood the series has
so I can reflect that in my wall.
Then again, I have a thing for walling my three favourite manga artists
1. Mokona Apapa (Clamp)
2. Kaori Yuki (Angel Sanctuary)
3. Yoshitoshi Abe (Haibane Renmei)
I think that anyone who looks at the walls I've made will see this pattern quite clearly. XD
The only times I really break away from this pattern, is for a contest or a requested wall. But the majority of my walls
are from these three artist ^:^
I always start with a scan I love, extract it... and then make a BG for it.
