This is an early panel from Slaughterman's Creed as it appears inked on the original hand drawn page:
And below is an ink splash I scanned (its in my Slaughterman's Creed 'tools' folder) and turned into a Photoshop brush. I now have my own custom 'blood' brush that I can change size, layer and shape around the art without making big splashy mistakes on paper (there's no undo when you cover up to much art with a big blob):
For the edited version below I filled in the blacks on the left just using a standard photoshop brush and the paint bucket tool, drew the tiles also using the brush (and holding shift which makes straight lines). I also added a bit of jitter in the brush options so the lines dont look too clean and photoshoppery.
I added the blood on a new layer with a couple of simple clicks (or taps with the wacom pen) on a seperate layer and erased the parts I wanted a little clearer. The blood being on a different layer also means it can be easily turned red at the colouring stage if thats what's needed. Lastly I used the rectangular Marquee tool and Stroke tool to tidy up the borders.
I'm away on holiday this week but I'll try to update on Sunday anyway. If not I'll update as usual next Wednesday.
