This is amazing! Not only a wondrous display of depth but also so mesmerizing to look at. At first,

I thought it was dream type of picture but then I noticed the background outside of the tunnel and

now I'm thinking maybe it's the ancient bones of a giant serpent or something. I love pieces of art

that paint a picture in your head and make you want a story behind it, you've definitely done that

here. Love the little orange alien plant in the bottom right too, nice touch.
