I have never had trouble with any actor being able to visualise things. They are amazing. As long as you have your monster head on a long stick so you can hold it up there and you can wave it around and let them see it and explain it to them they are just great.
You can always improve on something the technology is different today but I would leave it well alone. If there was something that was incomplete that might be interesting... because I do that on my website.
