Arrghus WIP (Link's Awakening/Oracles)

[Garamonde]

I actually think the top-middle and top-right colors look the most like rocks, because of that sharp contrast between the peachy and darker brown shades.
Although this also seems to cause slight readability issues with the black lines so maybe the bottom-right might work also? I think it's that darker brown that makes it look like rock so hopefully that helps somewhat.
