I wanted to test my ability to fully integrate VFX in Blender. A “reflection catcher” isn’t a feature yet 
so I used RenderLayers to my advantage to capture reflections as well as shadows. I added a simple animation to make the scene a little more compelling (the rain is quite distracting, which I mitigated).
Many thanks to the mannequin model by jgilhutton (https://www.blendswap.com/blends/view/74733). The stock footage is from (https://videos.pexels.com/videos/wet-leaves-on-street-rainy-852027).
I hope you like it. Constructive feedback or questions are welcome 
I’ve thought about a mini tutorial/workflow video, but I don’t know the interest level. But check out some of my other videos/art via the signature links below.
