Hello, it is the original psd. I was just drawing into a single layer.
I am very sorry it does not meet your needs. Maybe request a refund?
Yes that would be brilliant. I did not look at the buildings yet but they are done perfectly, all parts and shadows in separate layers. As a general rule of thumb, if it has a different color, we love it in a separate layer so we can change it at runtime. The larger/detailed the object, the more important it becomes.
Apologies for filling up the comment thread, i could not find an email address. Feel free to shoot me an email if anything is unclear still.
