In the picture you posted, your head is at an angle. It looks to me like the upper lip is swollen and the chin is in a line with the forehead. I think you just need to give it more time before you make a decision on your results. Stuff is still changing.
I wouldn't say chin alignment with the forehead is a good measure. Before my chin wing my chin was in line with my forehead and looked recessed as f**k because of general facial projection. In my own experience chin positioning comes down to a few things:
IN CASES OF SLIGHT BIMAX PROTRUSION
1. If upper and lower lips align, the chin must align with them, but not more.
2. If lower lip is slightly behind upper lip then the chin must align with the lower lip, but not more.
IF MOUTH IS MORE OR LESS FLAT
1. Chin should at least align with lips
2. In many cases these face types can look good with a chin that projects beyond the lips similar to marquardt masque.
Also, upper lip swelling is real. You won't know until a good 4-6 months how the true result is.
