Any thoughts on my posture?

Always procrasionated to fix my upper back. Only half a year ago did I start to do some exercises focusing on lower and upper back, shoulder blades, and of course the hunch itself.

I would like some opinions for what I've posted:

● Photos 1&2: How is the size of my hunch? Do I still have hope for a neck without the hunch? What exercise could I do? I feel like my shoulder blades protrude. Or are they supposed to be like that? Could I "flatten" them? Sometimes, a shoulder blade really pops out if I lay on my side in some sort of position. Rounded shoulders? Yup! Forward head position? Yes, but I don't think it is as so intense.

● Photo 3: This is how it looks if I put my head back and chin up, shoulders back, and stand on my tip-toes. Seems alright. Would it look normal if I start walking with my chin pointing up like that?

● Photo 4: How my upper back looks like when I push my head and shoulders back with all my strength and stand-up straight. What if I lose the additional fat on the shoulder blades and hunch?

Exercises I've been doing in attempt to fix my posture and hunch: ● Lat pulldowns ● Roman chair back extensions ● Shoulder squeezes ● Those pec stretches using a doorway ● Daily walks (5km) and weekly runs (up to a total of 5-10km) with a straight back as long as I can maintain it for.

Thanks in advance!
