Nice, but the dithering is not the best I've seen - what process do you use to create the final images?
I've recently read Eden: It's an Endless World! by Hiroki Endo on the prs-505 and the dithering/general image quality produced by FangornUK's comiclrf script definitely looked better, perhaps you could run your source images through that?
For the rest it's great, but I've always been a sucker for CGI and manga, so any combination will sit well with me
