Thin line work, practically zero shadows and shading, but his characters are expressive in both their faces and body language.
One thing I watched out for in the trailer was the potential return of speed line backgrounds. Not only did I not see them, I didn't see CG backgrounds either. All the backgrounds seem to be drawn for potential animation, and I'm looking forward to that.
