I thought about this one a lot. It is well observed and taken but needs some work. IMHO the brightly coloured flowers take all the attention and as the shadows are supposed to be the focus of the shot that doesn't work. I had a play with the image and there are a number ways of dealing with this. Cropping the flowers out and cropping the superfluous lamp top at the bottom, sharpening and upping the contrast gives a pleasing image where the shadows are the stars. This can also be converted to a mono image. Leaving the image uncropped, sharpening etc and converting it to a Mono (yes this is me
suggesting this) takes the emphasis off the flowers and places more focus on the shadows.
