Abstract city

I wanted to represent a mysterious city giving free rein to the imagination. Some of you will see a space city hidden between nebulae, others will maybe see a futuristic underground city.. Don't hesitate to tell me what you see in the comments! My creation process for abstract works is quite chaotic. I don't have a guideline. I usually paint a background to create an atmosphere. Then either I use a multitude of photos which I destroy entirely to create something new. Or I use the previously painted background which I duplicate and modify a lot using effects, filters.
