I'm a newbie (not really). Which are your recommendations to transform sketches into images?

Due to my university thesis, I need a Generative AI tool to transform my own drawn sketches into photographic images keeping the exact same composition. I was so deep into AI a long time ago, but I know nothing about new models or platforms for this kind of advanced AI workflow. The latest I knew was about Stable Diffusion XL, SD3, ControlNet, ComfyUI, and Flux. And since I don't have a powerful computer, I'd prefer for using relliable online services.
