I don't always do this but this time I decided to go over the gross outlines with India ink.
This makes it much easier to keep track of my drawing as I start to paint over it.
Both charcoal and India ink can be painted over nicely without bleeding through the paint.
Something like a marker will bleed through and ruin your art so don't do that.
I also didn't like the awkward space between the Queen and her prisoner. So I made the only obvious
choice there was which was to put a giant multi-limbed salamander dragon thing in there. His long
sinuous shape ties the whole image together and guides the eye towards the center of the drama.
