Thanks! I never know how to explain or analyse my work, because when images pops up in my head I really don't know were they come from. But if they look nice I try to visualize them in detail, knowing exactly what I want to achieve before I start working on the picture. With this one, I also saw a possibility to read a deeper meaning into it, if anyone likes to do so. After checking the definition of the chess term Critical Position, the name was obvious.
