Can I train Midjourney with my selfies to create professional portraits? Need advice!

Hi everyone, I’ve been blown away by Midjourney’s capabilities and I’m curious about using it for a personal project. I’d love to create professional-quality portraits (e.g., for a profile picture) based on selfies or photos I’ve taken with my phone. Is it possible to ‘train’ Midjourney with my own images to achieve this? Has anyone tried something similar, and if so, how did you do it? Any tips or guidance would be awesome—thanks!
