With this Project I tried to capture kind of like a New York alley. I mainly did this project to learn texture blending, the use of decals and how to use imperfections to make a scene more realistic.
First I did a rough blockout of the scene, then added the windows and fire escapes.
After that I handled the lighting and I added all the rubble, trash and decals like the manhole and the graffiti.
Last but not least I added the rain and made some changes to post processing.
In this Picture you can see the texture blending.
I used a brick wall texture as the main texture and blended in some industrial and rough concrete to make it look a bit worn down.
Here you can see some of the decals I used like the graffiti on the garage door or the asphalt potholes.
