The aircraft are not supposed to be to scale, right? Because I don't think J-20 is that much smaller than JH-7...
And it is also a little weird that the artist chose to keep some of the formation stripes on planes like KJ-2000 and 200 even though they only bore them during the 2009 parade.
Also, I think Y-8G is stand off ECM rather than SIGINT.
Good drawings otherwise
Honestly we are just discussing that issue ... and Tom - being a brilliant author and even more artist - can be quite stubborn sometimes.
I already told him that they are wrong, either the J-11, J-8 and JH-7s are way too large (these three match together quite fine) but all others are even more too small in comparison. Right now we are discussing how to handle this, what source is correct for what type and so on .... and after that I really don't think that I can persuade him to add additional types.
I will show You the latest corrected preview when I won this battle ... and I will fight hard !
