Looking quite awesome! I started in Secondary too, and 10 years later - still working with Unreal and trying to push myself!
Like , I don’t have the time to watch it through either, which is unfortunate - however I’d like to start by saying your work is coming along really well. For starters - the first thing I would say is that no Shadow is ever truly black, and there was one or two instances where I’ve seen that. I’d recommend (if you’ve been looking into the 3D aspect of things) to learn how to lightmap your objects correctly, this will stop things like: The bottom of the plant at 1:13 and the same for the couch and casting a shadow on the carpet at 1:26.
At 1:50 I recon this is where the biggest fault lies. This scene has no indirect lighting and even in a darkened contrasted scene - no shadow is ever black. There is always bounce lighting off other surfaces! 
( look into Area Lights, reflection cube and sphere actors, and on your directional lighting outside the window increase the Indirect Lighting Intensity to 1.0 to 6.0 and see the effects 
)
Please keep in mind all of this is constructive criticism, don’t take it to heart - use it as a learning tool!
Really awesome job, kid. Like others have said, you’re definitely destined to go far here.
And welcome to the community! I hope you feel comfortable!
