Well, the nose looks almost the same
Saw a few comments which claimed that the nose looks to be bigger.
Though, from what my eyes can tell, the nose does look to be somewhat protruding-ish from the rest of the airframe, though not necessarily bigger than other Y(Y)-20/A/Bs.
Perhaps my observation also has something to do with the poor quality of the photo, though we can only wait for clearer photos in the future to be sure of that.
but for the tail I‘m not sure if there are only two fins attached or if there is even a bulge/array on its own?!!
There is definitely something mounted at the tail section, as noted in one of my recent posts.
@斯文的土匪-- on Weibo believes that module to be a large EO sensor system, which is similar (if not larger and more powerful/capable) than the one mounted on the nose of the KJ-700. Though, the exact build and purpose of said module remains to be verified.
