Put them on fire. Light them up on fire. Draw fire over the rocks. That's what I meant.
Btw, my project only needs to finish a small gap in the terrain, and once I finish the story I'll just connect the storyline quest-by-quest then boom! It's finished. But alas, other plans always get in the way, so it's going to take me a while.
You're already making the UI look great, so I think after you apply my suggestion then you finish the upper part, it's ready to go.
