I have a class 1 bite.
My chin doesnt protude at all from the side profile, is that not a weak chin?
It seems like it is mainly my jaw which causes forward growth of the lower third
Common Asian trait is BI-MAX PROTRUSION. It's when the front teeth ANGLE OUT a lot. It's seen by the LIPS also ANGLING OUT a lot (lip protrusion) which is seen in your profile. Bi-max protrusion, especially the protrusion of the LOWER teeth (which protrudes out the lower lip), can make the chin look relatively recessive. Someone with Bimax protrusion can still have a class 1 bite.
So, you MIGHT have that. I think it's most likely reason your chin looks recessive to
you. You have good bone structure, Class 1. So the bimax is NORMAL for Asians to have. THAT is WHY I don't think your chin is 'recessive'. I think chin augment with the bimax lip protrusion could look weird.
