i used watercolor paint, and fineliners and the posca white pen.

Also I used grey toned markers and added color here and there with color pencils.

I wanted to create more detail in the brick walls and experimented a lot to get the brickwork I went a little bit overboard I think with adding perhaps to much different mediums?

I let you decide and perhaps share a tip with me about that?

Thanks a lot and good luck with your projects!
