I mean, that's one way to do it. But I don't really want to put in pictures of real-life people, especially since nobody would be fitting for it. And AI with Text to Image doesn't work the way I wish it would.
Btw I find it interesting that you wrote your own screenplay. I don't think narcissism is inherently a bad thing for actors, though it's not a positive trait on average, you have to be a bit narcissistic to spur your own performance, to want everybody to see you and not feel ashamed. Not that that can't happen anyway, but I believe it's the best carreer path with this trait. Also, just because you have the ambition, I wouldn't even call that egotistical or anything like that. I hope you will actaully land some sponsors to realize your play one day. I'm rooting for you.
And yes, that thing about the patience and time to draw is basically it. At the same time, I have a problem with drawing anyway, so it's not JUST that. It's not like I can't draw at all, I went to an Art school once upon a time, but I have the problem of my brain being incapable of remembering shapes. When I understand something, I can somewhat reciprocate it, for example, once I understood anatomy, I could draw a body. Before that, I could tell you a person has two arms and two legs, but when trying to draw them, it looked odd. As long as there wasn't some real person standing deadass next to my easel, I couldn't even tell you what looked weird, because had I known, I wouldn't have made the mistake. That's where we are at, I can't tell you what a human looks like, unless I have one in front of me. Just a random story, to paint the picture of how bad it is with my shape recognition. I'd probably do a good Picasso, but even Picasso I couldn't copy unless a picture was next to me.
Anyway, I can't even explain something in a more or less concise way, unless I look at it directly. Which is why, ironically, I try to realize Tattoos or certain objects, in order to be able to describe them in my story. Before they are on paper somehow, their shape just changes in my mind, it's as if I see it, but I don't really see it. On that note, I'd be intrigued of what other people saw if they were able to peak into my mind. I would never be able to draw a character twice the same, which is also why I couldn't do a Manga or Comic. For something with more details, as a person would be, having someone else fill in the blanks, when I'm like "It needs to be like [this] and [that]" is way more effective and makes more sense.
Sorry for that rambling rant here, got longer than I thought it would be, but It's annoying to me that my brain doesn't do what I want it to do. It's frustrating.
