Heya, I really like the blending of the characters. The way you arranged them looks like it's always been intended that way and not a mix of several scans. The light filter works well to help blend the characters further.
The Mashiro scan (and to a lesser extent the other characters) show the telltale scanlines from printed material. Cleaning those up more in the future would help. And this is just personal opinion but the pink/greenish noise in the darker areas of the background reminds me of digitized video rather than a neat grain effect but that may just be me! :)
Overall though I really like it! Thanks for submitting it!
