Hey, 4 weeks is really still way way too early to tell. I am one year post op now and from this vantage point, I can tell you that I looked WAY different now than I was at 4 weeks. Trust me. I obsessed and agonised over my face as well for the first few months post surgery and even went back to my jaw surgeon asking for a reversal, but now, one year later, I realize all the upper lip protrusion, the distorted nose, the swollen cheeks, the terrible smile - they were all because of the swelling.
Let your face settle for 6-8 months then see how you feel about it. I also have some canting and bite issues but my ortho is able to help quite significantly, and also because I want to avoid another surgery. My results are not perfect but I am happy enough to NOT risk a second surgery to fix what are minor "imperfections".
Good luck and I hope you will grow to love your new face like many of us here did! Remember: IT'S JUST SWELLING!
