I'd quite like a 'common pitfalls' video regarding Pop UP submissions, though it doesn't have to be live. Writers often seem to make the same mistakes in their opening 700 words - telling not showing, too much backstory, not enough happening, writing themselves in, info dumps, over world building up front, instead of more organic insertion through the novel etc. It would be great if examples of great openings could be shared and analysed as to why they work too. This might help people refine their openings before submitting.
