I was just looking through the XIV variants and I'm not sure if you see it but to me, the Sunder looks a little out-of-place aesthetically when next to the other XIVs. I think it's the lack of lighter tone on the hull, as with the others. They retain some of the original colour and have definitive striping whereas the Sunder is practically all orange. The orange on the Sunder could also be a shade darker, it looks a little too bright.
If I was any good with GIMP, I'd happily do this myself but I'm terrible with such things.
Obviously, it's just personal preference in terms of design but the "ex-pen and colour artist" in me can't help but notice these things.
EDIT: In fact, the original XIVs (Enforcer, etc) could do with a face-lift to match the new striped ships perhaps? They look much better than the old ones.
