I like the rounded crosses used in Gothic architecture. I also like the multiple columns on each side used to frame an entranceway. I'm not sure what I prefer (a perfectly rounded doorway or one that comes to a point like this one).
Paul Kenton's 'Taxi Lights', uses cold tones to evokes a dismal tone throughout piece despite there being inclusions of red and yellow (amber) to subtle spots of warmth to the piece. It overtly creates a miserable, and dark association.
