I'm liking the different colour palette choices being thrown up here. Essentially the choice will come down to the person who commissioned it, but it's good to see people's take on a Cthulhu palette!

The one by kalmarjan really should have a load of insane scrawls on it to add to the mood.

Sigurd, I see what you mean about it being clearer. In the .xcf file all the colour layers are currently down at about 20% opacity, which accounts for the washed out sepia tone - possibly I went too far. The lines are a mix of low opacity overlay layers andmid opacity normal layers too. I'll have a shot with greater colour definition and see what it looks like.
