The Floor Is Lava

Not quite sure what's going on with the thing in the sky but I like the landscape. However, it'd be great to add in more detail on the rocks, especially on the hills. Use reference. Work on those splashes (?) a bit more. And I'd prefer if you changed the color of the sky to blue. Orange and blue are complementary colors so it'd keep the drawing more interesting. You can throw in a gradient and put a filter on the texture or just mask it, if you'd like. Or you could use a redder color to show the heat that the lava is creating (see mustafar).
