Obviously inspired by my fav fighter jet ever, the Su-37/47 Berkut. Warhammerized it to hell. Dontcha wish GW made something like this? Not in your lifetime tho. But, one can dream of a proper Chaos Guard.

Though it will probably get quite expensive to 3D-print something that big, your fighter will probably outgrow a Thunderbolt.
I think, by rule, GW would have to ruin the design with spikey bits and ornamentation that take away from the vehicle's integrity.
Imperial stuff is boxy, Tau is mecha-anime, Necron is boring...etc...
It shouldn´t have visible bolts and smooth like a razor, after all the Xanthians are technologically superior, far less sloppy in their work than the snivelling servants of the false Emperor.
Still, the half-starved pilots of the Imperium knows their metal boxes are their coffins when they go against such fighters.
Of course, they pray, beg the Emperor to save their worthless hides but their fighters are still burned to vapour, sending their souls the Daemons of the warp, lol!
