Hi there thanks for your comment, about the light I just used an HDRI map in corona enviroment.
The settings in Corona are all default settings.
I just start with a plan a car and than I decided to add some baloons done in CLO3D.
Tha grass is Corona scatter.
The post is part in AE where some time is easier achieve some good color correction and than photoshop to paint some fake light and a little bit of blur on top, plus the BG that has been replaced.
Nothing particular in this process, the composition of course is not great, the bush (that i dont like) are done with some tree under the terrain level.
That's it.
