Task 2 COMPOSITION - Trip to Uttoxeter

Armed with the Canon 450d camera and 18-200 lens I noticed this shop window with its eye catching display.  It wasn't intended to be a frame within a frame shot but I have selected it as one.  On looking closely into the picture you can see the double yellow lines of the road in front of the shop window.  I took three shots, the first two at shutter speeds of 1/100 and 1/50 and aperture of 6.3 and decided this was under exposed so I slowed the shutter speed down to 1/30 and set the aperture to 4.5.  The focal length was 33mm.  The time was 18.27 pm.  I feel this gives a good balance of the colours in the shop window; the white of the curtain isn't too white, the pink is just right and the black of the handbag is such that you can tell what it is and it doesn't blend into the background. You can also see the pearls on the bag.     The under exposed picture is shown below.  Looking back on this picture now, 3 months later I do wonder if it is obvious it's a frame within a frame - should I have got some of the window frame in?
