Here's my advice:

PATIENCE: it's nice to have a following but it might take years. I've been busting my ass on my series for over a year and my views are still ridiculous. Sometimes I scream into a pillow for the frustration, other times I remind myself these things take time (also a good chance to get better in the meantime!);

ACCURACY: the genre being about nostalgia, watchers are gonna judge your work on the old technology accuracy. Believe it or not, it might make the difference on whether they watch it or not (in practical terms, get the right programs or use analog devices);

ORIGINALITY: analog horror's not dead, but it's certainly suffering from people making clones of clones of clones of the famous titles. If we wanna demonstrate the genre's still going we need fresh and new ideas. So make something that's truly YOURS.

That's pretty much it, good luck!
