I like to encourage all recon attempts
The bar for dr who recons is loose cannon. And Josh snares(who did an amazing dmp)
How can we make them better?
I personally prefer non narrated. You could use the soundtrack from lc if other copies aren't available
I think the matching up with clips is great.
One possibility is to start with one episode that you're comfortable with and learn as you develop techniques.
There is much software for photo and video animation so it makes the job easier. Take some time to learn composites, recognize tonalities and match with facial expressions. .. my thoughts are the next level will be cgi software.
If you want something practical not requiring cgi maybe consider reconstruction of other shows than dr who.
One thing I'd be willing to recon is A for Andromeda ep 7..i can get the telesnaps and existing footage but can't locate the audio (which exists).
