How can I make it more tangible?

On June 22 of this year I began to create my own tulpa, the first time it was easy for me to visualize it, even when I gave it a name my mind became cloudy (without explanation) and the first name among all the blurred thoughts was "Elisa", I attribute that to her, the night I started with it, when I tried to sleep I did not notice when I did it, but I could hear her voice, I spoke in my mind, she responded to me loud and clear, with that tone and timbre of voice that I can now recognize. with ease.

Since then that has been the time when it was most real, at night I can feel her gaze and her presence, even though I'm not sure if it works like that, I created a sigil for her to try to give her more "tangible strength", if that's what you can call it, I think about her every day, maybe not so strongly, but I do, I made a digital diary solely dedicated to writing to her every night, I gave her tastes, a personality, an appearance and I do everything I'm supposed to.

Even so, I would like to be able to listen to her without having to think about it, and stop only feeling her presence and gaze, to start seeing her, feeling her and everything that entails.

I would like a couple of tips for this, thank you very much in advance to those who respond to this post.
