playing with screen-like-tones

I have been looking at a lot of anime and may have to do 8 pages of a story that should have a manga feel- I wanted to play with screen tones as a substitute for  gray-shading black and white images- I started playing around with filters in photoshop- specifically the halftone filter. I created a couple of versions of this in a file and place the file into my image.... I then scaled down the file and duplicated it several times and tiled the images, then reduced those down to one layer... if the screen was too opaque - I reduced transparency to 45%- I did a quick and dirty selection then cut away the inverse of the selection to get a sort of friskette... I wanted to treat this layer similar to a graytone layer so I cold either blur the edges of the frisketts or erase edges with low opacity soft eraser--- I still need more work before I can put this into production...here the image
