Wow, gorgeous. The details, the linings and the tone just caught me. Especially like the tonality. #2 is unique by itself where the curvature,the lines and the grain feeling on the surface reign and take over me watching it. #1 is a bit of the space war feel where an alien is about to emerge. Just spectacular! I think I don't know how to shoot down there, aghasted at what I see.
By the way, how did you get down to the bottom of the cave? Probably, there is an entrance from the side. I presume you didn't have to be descended there by a rope or something?
