This workflow takes any image, resizes is to the appropriate SDXL resolution, automatically captions it and runs it through 2 Control-Nets and an IP Adapter to produce a Line-Art / Sketch reproduction of the image. I've mainly tried this with animals but should work for anything. Play around with the values for the Control-Nets and IP Adapter as well as using different Samplers, each gives a somewhat unique style to the type of Sketch or Line-Art SDXL-Turbo (Experimental) verison is available on my Patreon https://www.patreon.com/user/shop?u=18651445
