This was a quick project in Zbrush. I was a big fan of the movie and wanted to sculpt something that wasn't a production piece. 
I had a ton of fun on this and hope to do more quick Zbrush projects in the future. 
Everything was created in Zbrush. 
Render passes were put together in photoshop to create the final image. 
The background was a handful of images composited together.
