idea to enhance the text prompt with a second prompt that allows the artist to draw a sketch

hi, i'm an italian artist so sorry for the english. I wanted to offer you the following idea to enhance the use of your image generator product from a text i.e. other than using a text prompt you should allow an artist to draw a sketch of his idea and from that the image generator could then produce pictures. Using a text prompt to describe an image to your system does not give you as much control over the desired output however if you could draw a sketch of what you want and associate it with some text then you could create images that are closer to what the artiste had in mind.
