"Blank Stare" does meet the challenge of Master of Disguise. The shot really reminds me a piece I think someone did in the personification challenge. I had to double check to make sure it wasn't you.
I think your piece is a very nice idea and captures the image of something we might see in some movie where the tree comes to life and grabs one of the characters. The coloring of the shot is very natural. The little red dots towards the center are very small but still grab your attention. The composition is very nice. There is a complete eye with out other distracting additions. I also really like that you choose to you with a landscape layout instead of like a portrait, I think it would have taken away from the effect.
I think you had a very nice piece but voters were just hoping for something unusual that is not normally seen. Good work.
