Does this work well because you have anchored the bottom points in the corners but let the upper ones exit before the top - making your eye explore the background above and then behind? Just guessing....
@robz Hey...sounds good to me...wish I were that conscious! I was consciously not making it too symmetric and debated with myself whether the light area in the background was a distraction or gave this shot added value...still haven't answered that one. But thanks for giving credit for being so aware...even in not really warranted ...certainly boosts my confidence (not to mention ego!) :)
