Nice drawing. You did the reflection very well :) I think some crispy edges on the building would make it look better and stand out a bit more, same with the towers. I have a feeling that you drew the building and towers first and then added the background (sky) instead of drawing the background first, on one layer and the building on the other (incase you are not happy with the sky and want to change it's color, then it would not effect the building) That is just my opinion, pls don't get grumpy at me. It is very pretty drawing, well done!

you should post in intermediate.
