Second style frame for the "Museum of clouds" of project. This frame was made really fast and to say the truth the workflow about this one is not very interesting. I used freebie
vdb for the cloud, to open vdb use "vdb volume" from octane tools. To change size of vdb data change input unit in "vdb volume"settings. To adjust the structure of vdb play with "density" and "volume step length" parameters. Color scheme was taken from Kuler. Road lights was created using clone tool.
