I had this version and the completely B&W image on my computer for a couple of days, trying to decide which I liked best. This version won out, probably because of my impression of the corridor of a deep-space vessel and a sense of dark foreboding in the image. That led to my memory of 2001, and the suggestion of a HAL-like presence in the depths was born.
The red parts are easily eliminated if a customer (or me) desires - one of the advantages of digital art. But I'm happy that you like the image even with the red addition! Thanks so much!
