Yes, I think this is General Discussion material.

I haven't done anything like what you're describing. For form, at least, it sounds like a good idea, but describing personality sounds a bit odd. I can't see how it would help much with visualisation - despite what you said about it - and if you imagine someone talking to you about your personality, I think it would be unnerving at best.

I see the form pretty separate from the personality, really. I live with someone who looks really old, but he is still pretty young at heart. Very immature and oblivious, far from how one would think he should act. And I sure as hell didn't force those traits in, believe me.

For visualization, I did doodle and study his form on paper first. Not only did it help me to understand how he was made much better, it was easy to just think back to the images I drew earlier if I found his form to go blurry or I was losing track and couldn't get it back. He's a bit different now, but early on they were a great help seeing that I was still learning.

I think that something drawn would be better than something written so you can look back to something you actually see, but some people are better writers. Maybe you can see your words easier, so it would still work out very well. But for me, drawing definitely takes the cake.

Also remember to bring sound into this, didn't you say you had good sound imagination somewhere or am I thinking of some other dude? Use your stronger senses to help with the weaker ones.

Also an interesting thing you say about forms being separate from the personality. One of my tulpas changes forms quite often, and has even taken some object forms as opposed to living things, and she told me that forms are just there for show. Perhaps I shouldn't try to connect the two so much.

That's a healthy attitude to have, really. It's an imaginary form you can change just like that. Nothing special, hope other people would realize that too.

For the other stuff, yeah. The more you draw something, the easier it becomes. No need to wait when you can doodle already. If you can, drawing them from multiple angles is some great stuff. It might be hard to imagine the tupper spinning if you visualization skills are bad, but if you have the "key frames" so to speak, you can later easily learn how to fill in the blanks. I'm not that much of a writer myself, so I can't really give tips about helping you visualization that way. I draw first, write later.

Really, just a skill you gotta learn and practice. Keep at it, it's good to hear you're making some kind of progress.
