Bleeeeearrrrgh.

I ended up working back into the drawing a bit more, which is good it need a bit more refining, even though I have to turn this over quick.  There was just too much going on behind the pair. 

So here's where we're at with the color.  I'll likely do another variation for the client, but all is progressing well.  I'd love to add some textural effects to give it a feeling of age (thanks Shock Totem), but I don't want to ruin the clarity. 

It's keeping the feeling of an homage to the Chamber of Chills cover, which is good.  It's good to have a chance to work on something like this. 

Stay tuned if you wish for the final version, which may or may not have a slimy speech bubble.
