Invisible Cities: Low Angle Shot Progress

I think this is getting close to being finished, I still need to sort out the glowworms, add some more detail to the stalagmites on the ceiling,  blur the foreground, add more highlights, and just do general refinements and touch ups. I like how this is turning out so far, I'll look at adding some oranges like I did for my interior, however that didn't work out well for my exterior establishing shot so it may or may not look right for this but I'll see. Feedback welcome.
