Wireframe challenge solution

Good work, nice analysis of existing platforms (Youtube and Netflix). The addition of the video queuing feature is very interesting, as is the emphasis on sending comments positioned at the very bottom, reminding users of their messaging habits.

However:

1. I feel that the title of the video currently playing and all related actions (comment list, liker or disliker action, etc.) should be grouped together, to give the user a coherent reading experience (cf Gestalt laws of grouping - https://www.interaction-design.org/literature/topics/gestalt-principles).
2. the queue update functionality could be improved; since it's mobile, clicking on a corner of the video thumbnail could be both confusing and frustrating if clicking on the whole video would have to play the video. A better approach could be envisaged.

For me putting the recommended videos between the video and the title messes with the information hierarchy. Putting something in between the title and the video itself makes it confusing for users to know what they are looking at. Depending on the viewport you might not even see the title anymore above the fold.
