My newest work as of September 2013. Went for a very tall city buildings as a background models with mobile shooting game in mind.
I gave them tons of very small lights as a windows to give illusion of taller building.
As always feedback would be appreciated, and maybe more ideas on how to make them even more taller like a skyscraper.
