Nice work. I see what you mean about not knowing where to go, although it is modelled brilliantly the composition lacks a focus. Perhaps just a single book would help bring some clarity to the scene, I've often found reducing the number of objects in the image can improve the shot. I would be tempted to try just the book on the foot stall.

why is my kropped account hacked, I see a little tattoo'd baby in stead of my render?
