London's Sky Garden is a light and airy place, bright and spacious.  I have tried to portray these characteristics in this Sky Garden Blue Original Sketch.  There are large organic shapes, varied leaf forms in vibrant green and touches of colourful flowers.  These contrast the steely architectural strong lines and blue tinted glass.  
 
The sketch is drawn in watercolour pencil.  On some parts of the drawing, water is added to soften the lines, but I have tried to keep some of the detail that comes from the pencil lines and textured paper.
