looks good, great job! I like the details and the great texturing!!
The ground of the balcony looks a bit overpowered - it looks like a whole fundament of a house. Did you model from a original picture? For my static understanding there is a floor of ~50cm concrete a bit too thick for the balcony, usually. The wall, on which the balcony is hanging on, is les thicker than the balcony itself, i think; I would be interested, if it's from a picture or made from imagination. Nevertheless, great model and great model-skill!
