Have been a fan of this film since childhood (never read the book… it’s on my list on things to do during lockdown haha) and, though I love its trashy 80’s sci-fi feel, I was often jarred by a lot of the more technical issues you yourself mention in your edit description above. It sounds like you’ve done a thorough job eliminating/improving them and your passion for your edit shines through. Am also curious to see the newly added scenes (have never seen the extended version, except for a few snippets on YouTube), and how you’ve edited them in. A PM link would be greatly appreciated, thank you 😃
