Design ideas/help half sleeve

[jamesmwalker]

Hey, I've been trying to come up with some good designs to create a half sleeve with what I already have. It's difficult as you can see from the image. I don't really want to stay with the tribal style but I'm stuck on what and where to put things. I know I want a grim reaper somewhere, a skull, a bird, and maybe some script but I'm really stuck on where to start. Thanks in advance

Maybe come off of the ends of the tribal in wisps/shading going in to the reaper, skull and maybe some old vines or a dead tree coming off of it?
