impasto or light moulding paste

I'm trying out a technique I saw on one of Donna Downey's YouTube videos. I think she used light moulding paste - which I don't have. I used Impasto but I think it's too thick and stiff - anyway - this is where it is at, right now. I'm drying it off and I'm going to use Pan Pastel on the paste, maybe a little paint as well. We'll see.

and the detail:

I don't know if my Impasto was old and so not so smooth to work with or if lighter moulding paste is better. Does anyone have more experience with these important matters?

I'll of course show you when the page is finished....
