Hi Bernard, to be honest, the best way of getting a sketch effect for a photo is to use Photoshop or similar application. They faithfully reproduce what you have and apply the style to it. MJ will always add a level of its own interpretation, so the output never quite what you (I) want. If you want to try MJ, upload your photo to your own discord server, copy the phto link, then /imaging prompt: photo link, followed by whatever style you want. You'll need some patience!!
