What procedures could transform my face into the second image? (Photos)

Chin augmentation - either sliding genioplasty or chin implants. I personally prefer sliding genioplasty, where the chin bone is cut through an intraoral incision, advanced, and secured with titanium plates. It is approximately a 45-minute procedure. Chin implant is also a good option; however, they carry a higher risk of infection, in which case the implant may need to be removed.

In order to provide an improved definition of your jawline, I would recommend a sliding genioplasty to advance your chin and mandibular angle implants to enhance lateral definition. Another consideration would be a custom "wraparound" mandibular implant.
