Hey Ivan love your Chanel and what you’ve done to the last Jedi. I’d love a link to it if possible. Keep it up man. You’re a real inspiration!
There are 20 or so Fan Edits of The Last Jedi already finished and released just on this site alone (see the Star Wars Fan Edit and Other Projects Index and scroll down to the ‘The Last Jedi’ section).
Many of these Edits on here already cover some of the changes proposed by Ivan - and some of these Edits have a lot more changes too, whilst other Edits quite conservative in their changes. All Edits on here are available for free - without having to pay anyone a cent - as long as you own the official blu ray or digital download, of course.
As for conversing with Ivan - you’d likely be better off visiting him on YouTube - he only made a couple of posts here seemingly to highlight his work, then left, and then made a YouTube video about it with some strange/bizarre claims… that’s pretty much been it.
