yes for certain the pla realizes the amount of excitement in the general public about its pojects, that is why some of these leaks are seemingly so public, almost mandated in a way. for example, the first prototypes for high profile projects like the j-20, j-31, and the y-20 were never in yellow primer, but instead looked "dressed up" for display with dark paint and various insignia, and even painted engine nozzles on the j-20.

Hope J20 in the future has more advanced stealth engines which lower the IR signatures engines like the F22
Those traditional open hole turbofans should be replaced with more advanced version of indigenous engine
Plus supercruise is a must

The product improvement to F-4 were driven by actual operating experience after 1960. It does not directly address the issue of whether the original F-4 was developed in such a way as to gain a small marginal increase in perceived capability, based on how F-4 was envisioned to be used in mid 1950, for a large delay in the program schedule and overrun in program cost. In the specific case of F-4, it appears the initial program proceeded relatively smoothly and on schedule. Some troublesome features initially envisioned for the first models of F-4, such as an IRST to aid radar acquisition, were dropped to allow the program to stick to schedule.
F-104 was a case of USAF's notion of a fighter having changed between when F-104 was conceived, and when it was ready for service. F-104 was conceived towards end of Korean war as a light, fast climbing and fast accelerating fighter able to fight for air superiority over battlefield at supersonic speeds. Between conception and delivery of F-104 the USAF fighter concept focus shifted away from air superiority to air interception and air strike. As a result, F-104 found itself fundamentally designed for a different role than that which it must strive to fulfill in order to be seen as worthwhile by the USAF.
F-14 was definitely a case of USN settling for a lot less than was possible in favor of getting the airframe out to the fleet quickly. This is why initial batches of F-14 settled for the unsatisfactory TF-30 engine inherited from the failed F-111B program. The engine suitable for such a fighter, and indeed the engine F-14 was designed for, the state of the art P&W F-100 based F-401 engine wasn't ready on time, and the USN wanted the fighter in the fleet even if it had to settled for TF-30 for the first few hundred airframes. As it turns out, F-14B, the intended definitive version of F-14 with F-401 engine, was cancelled. So the entire F-14 fleet spent a great majority of it existence relying on the satisfactory TF-30 engine.
F-14 is a interest case for analyzing whether it is better to stick to the original, ambitious aim at the expense of scheduling delay, cost overrun, and possible comprehensive cancellation of the entire program, or to settle for a half-assed interim solution, and risk being stuck with the half-assed solution for much of the program's entire existence.
F-15 and F-16's main engine problem didn't so much have anything to do with being too ambitious and accepting delays and overruns for marginal capability increase. It had a whole lot more to do with piss poor program management which encouraged Pratt and Whitney to over promise on the capabilities and schedules of the F-100 engine in order to get the sole supplier contract for next generation US fighter engine. Once P&W got the sole supplier contract, all of incentives to take the costly steps to make F-100 engine live up to full promise disappeared, leaving the USAF in the lurch with a fighter fleet equipped with a over promised and under delivering engine, without much leverage on the engine manufacturer to rectify the situation.
Once the congress resolved to bite the bullet and fund the development of GE F101 engine into the F110 alternative fighter engine, Pratt and Whitney promptly got its act together and rectified all of F100's outstanding problems in short order.
The performance of military procurement process is influenced by very complex interplay of factors. It is not often easy track down simple, generalized reasons for why they succeeded or how they performed.

nice! I think those pictures are the best closeup of the J20 we've seen to date.
Looks very much like a detailed 3-D CG model to me.
Looks real pictures to me. There's lots of detail there and the general feeling just isnt CG like
