I while ago I found a digital artist and photographer on F-stoppers that got me excited about this kind of composite editing where one uses different images (some which I created myself) and combine it into a final edited scene like this one. I won't mention his name because of my insecurities. Haha. My clumsy effort should not be compared to his amazing work. Nonetheless his work has gotten me excited to try something new. Below are a few of the images I used to created the final pic. The car, foreground rocks and water was done in my living room.
I have lots to learn but really enjoy this creative process.
