Mysterious and attractive picture. Reminds me of some strange short stories by the late writer from Argentina, Jorge Luis Borges. One wonders what is written on the panel of the left side... Congrats.

DG, this image certainly offers a lot of mystery, as Yves noted. To me, there's a possibility that the hallway goes on ad infinitum. Is it my addled brain or do I see hints of sepia? - - My best always, michael

The lines mark my entry then lead me into the tonal value changes. Excellent work, Daniel.
