@st0ven I see what you mean, the rest of it looks rather plain compared to the tree. By foreground, you mean the black ground area right? I don't know how to detail that because the black is the darkest color and the cave background is the second darkest color. Here's the palette I'm using:

Since I can't add a shadow to black, I'll have to detail it with highlights, but I'm afraid highlights would make the ground look too close to the background color? I kind of wanted to keep the ground cross-section area black, because the cross section would not be visible at all to the character.
Or maybe you meant I should leave the cross-section black, but detail the top green area? (I should change that to blue, no grass in a dark cave

) I might try adding stalactites and stalagmites made of triangular tiles.
@Gamer36 Thanks
@PypeBros I'm afraid I've never played that game. Although now that I think about it, I did use a photo of a park ranger and a photo of a chain link fence for reference.
