Nice concept and composition man, the only thing is that I feel the ambient too cold even thought there is lava, I don't know if that was your intention but it seems somewhat off to me, maybe makes sense if the shoot were outside like a tall mountain(?) but because of the stalagmites I suppose it's inside of a cave or something, and nice use of textures, maybe too much in the center background (maybe paint over it just a bit so doesn't look like a photo).
And really looking forward for more work from you man, very inspiring :)
