This photo is so well composed and the lighting is wonderful. It is a very interesting subject...even though you know an anthill is a chaotic place this picture looks so serene and peaceful. I think I would give it an even higher score if it were in a different challenge that suited the subject matter better.
Very nice lighting. I can see that you may have been able to shoot this from a number of other angles and likely got just the right lighting with this very well done... My sister told me that she would like to buy a print of this.
