Now i'm sure I've got the full concept for this image in my head, I am starting on the digital painting. I plan to put a lot of detail in the lava, as it is the focus of the image. At the moment,I have created a plan to show the scale,and am now adding some odd details to map it out. The orange is where the lava will be resting and the grey is the back wall, where the cavern exit will be. I'm hoping to progress with this today.
