Definately abstract. I think I could have guessed what this was, especially with the title, so maybe a little lose on the challenge, but still abstract non the less.
The color is nice. The photo is just not holding my attention much. I think that the area in the lower right appears to be the main focal point, since that's where all the lines are drawing my attention to, and that area lacks visual appeal. It's hard to critique the technical aspects of an abstract, but your focus looks good. I wonder what this would be like with a soft focus? Maybe give it a more abstract feel or add something of interest?
Overall, I think it's very representative of an abstract, but lacking something that really holds my interest.
