I am taken by the colours. I mean, even down to the little flowers in the dress going with the bricks in the background, the window and sill with the door and weather seal, all with the dress and trim.... then from the dark hair on the far left to the dark shadow on the right. Excellent dress choice, composition, framing... great job with the colours.
Like the balance in this photo. Background and foreground balanced with your black shoe and hair,camera. Also content is balanced with a beautiful female figure and beautiful gadget being the camera. Very elegant.
The composition is strange because it's a difficult one to pull off. Normally a face on the extreme left of the image would complete unbalance the composition - especially with the strong diagonals pointing towards it (formed by the right-hand side of your dress and your knees, and by your leg) - but the central shoe and the two strong white vertical lines on the right (the edge of the door and the other vertical) balance it out. It just really works.
