The Terrier's new shrouded variant appears to use the same "donut ring" design approach as Porkjet's tank butt from his part overhaul, but it just doesn't do it right; the tank butt on the Terrier Porkjet made had a nice metal finish with some detail, and looked actually functional. The current Terrier's shroud, however, is in fact clearly just that, a shroud, which is a problem because it retains the donut shape, making it look out of place and nonfunctional (especially when you compare it to the engine it's actually a part of, as the current Terrier looks very functional and tidy).
I would recommend either making it a proper tank butt like Porkjet had, or making it more like the Spark's shroud (perhaps with some of that gold foil for a nod to the original).
