With all of your AE compositions rendered out, compositing is very straightforward. Each animation stands on its own, so I avoided dissolves between the shots. The main task in the compositing application is to sequence the animated clips.
Keep your original stills, your PSD files, the AE projects and your rendered animations well organized. You will usually find yourself often going back to tweak animations and then previewing the final results within your compositing timeline.
I hope you find these techniques useful in your ongoing quest to produce more compelling content.
Caption: Use music and sound effects to help tie together your animation sequences.
