Since we're doing artists' concepts, here's mine. A bit ungainly looking, with a certainly ugly hump under he belly, due to the weapon bay. But otherwise I'm pretty happy with the general compromises made. Amount of fuel carried (prioritized), size of weapon bay (single, centerline), ground clearance, as well as overall lines. Should be right up Chengdu's alley, basically an amalagam of J-10 and J-20. Still looks fairly sleek. Hopefully with the long enough/spacious enough inlet duct and WS15 class engine one could remain hopeful it's supersonic agility and speed remains similar to J-10.
