Without outlines? Okay then
It's been a while since I did outline-less work, and the last time I did I used the burn and dodge tools. This time I'll be using the paint brush at low opacity, so it'll take more getting used to. But, Shadow's dragon form is a friendly colour to me, so hopefully it won't go too badly.
What I'm doing though, is I'm doing all the black outlining first, then I can use it for guidelines. And, if it doesn't work, at least I already have the lines and can start over with the colouring.
Shadow: Horses? *Looks around* I see no horses.
