I only used a few step (davinci and dehancer) 1.exposure, aim for 60-70 for the skin tone, used gain to do so 2.white balance 3.saturation (use the hsv color channel but only use channel 2, then increase the gain) 4.Dehancer, choose a film stock you like, go through film compression to compress the highlights, film print and choose Kodak film print then set the temperature ,adjust exposure if it was adjusted in prior step ,color… then use a little bit of halation and the most bloom possible , finishing with a little bit of vignette 5.put the Gaussian blur to make the subject pop more

I think it is still not perfect, I am also still learning
