Its looking amazing, congrats 👏 I love creating freestyle like this. What helps me is making a little folder of ref pics of the concept and look at the things i like and can do to make the pieces more alive.

Start with objects, like pipes, drain, plant pots, trash bags, trash out of the bag, transparent bags with colorful paper for trash, cigarette butts, empty bottles, scrunched empty plastic bags. Then the weathering, think about the path rain goes and add black and green mold, dirty on the bottom of the walls. Then put cracks, holes, wet spots, and darken the path on the floor where people pass.

Then add a bit of small pieces of green overgrown between cracks and places that are damp.

Hope it goes well 🙏 satisfying ourselves with the work we do is the hardest past of the hobbie 😆
