i think it looks like design has basically froze by now. Next major changes would be engine change. The next question is how many more of these pre-production prototypes they would need to build. I guess we will see over the next few months.

I noticed that as well, but didn't say anything as I couldn't be sure if it was just down to different height between pilots.

Although there was not much head room on the older J20 prototypes, which might have pose a problem for taller pilots, especially if they also wear the new HMD.

Aerodynamically speaking, the new canopy shape would add more drag, but I think it m

I'm glad they changed it. I was feeling claustrophobic for the pilots.

There was a picture from years back of Jiang Zemin playing around with a joystick to control a Chinese TVC nozzle.

By all accounts, the PLAAF were not that impressed with Russian TVC, having turned it down when it was offered with the AL31FM3s the Russians supplied for their J10B fighters.

As far as I am aware, they consider the benefits offered by available TVC tech to not be worth the reduced thrust and increased maintenance costs that comes with TVC.

Then you tell me why China bought 24 Su-35 ??

Those pictures in CJDBY.net were taken by the famous Adam.Y.
They must be taken from his favourite spots around CAC perimeter.

If Adam.Y is visiting Sino DF, I would like to express my HUGE
Gratitude for all his efforts and sacrifices for taking those pictures for us.

Where is JayBird ?
I hope he is doing fantastic and everything is ok.

-Off topic-
There are many possible reasons and trying to simplify the purchase of the Su-35s to only a single reason (such as "TVC") is not very conducive to good understanding.

We should view this purchase not only in terms of the capability the Su-35s bring -- because their capabilities are somewhat limited, given the price of buying them, especially in context of the current state of Chinese fighter aircraft (not to mention new fighters that will very soon enter frontline service such as J-10B/C and J-16) and their force multipliers such as AEW&C and EW/ECM planes.
Other reasons include demonstrating its willingness to cooperate with Russia on defence matters in a greater way, getting access to some recent Russian technology just to see what they've been up to (possibly including TVC, but also to have a look at other technologies such as radar, materials, etc), and also simply getting additional advanced Flankers to supplement SAC Flanker production.

In other words, there are probably a whole host of reasons which must be taken together to rationalize the Su-35 purchase, and they include geopolitical reasons as well as the capabilities that Su-35 bring, as well as possible interest in looking at certain Su-35 technologies as well. No single reason is likely to explain the purchase alone.
If this purchase of Su-35s occurred in the early 2000s then China could have gained a lot more from 24 Su-35s both in terms of capability and helping their own technological advancement, but now the benefits a mere 24 Su-35s can bring to the Chinese military aviation force and the industry in terms of technological advancement is far, far smaller.
