I worked on this piece for three weeks, the first and the second week i created the idea and collected the stock images and i masked all the buildings and set the light and shadow in every one and i did some retouching. the problem i was facing that i didn't find a background for my work, i looked everywhere but i couldn't find what i was looking for, so i painted the background after i took a couple of tutorials about perspective in painting, it was a little hard. the last three days i started working and blending all together set the light ...etc. it was one of the hardest, so i hope you like it
