Different authors/designers come up with different ways to make things work. The design for the Earther Warships work for them. Fairly well. So sod off from the slacking, you want to voice your opinion, you can email the author...it's on the website 
As for the availability in the UK...I'm not sure...once again...email the author for more information.
I'm sorry, but.... these things don't exist in reality either. All this... sci-fi, it's just the extrapolation of a wild idea. sometimes founded, and sometimes pulled out of the air.
So I don't see any excuse for not using artistry to make something look good. Look at the Wright brothers flyer, and compare it to a Concorde or an F-15.... how similar are they really? People can't even predict 20 years into the future, so don't throw out the 'it's artistically dull but it's realistic' excuse.
To me, art is about ideas; a box doesn't have any impact...any scale....any sense of purpose, of ideas, of humanity or otherwise. It's a box; I look at that cover, and I can't imagine anything like dynamic action, or a fleet of these things in massive battle, or performing heroics, etc. I imagine a box of tissues, same as the box sitting 2 feet away from me
right now.
So I don't like it.
And I'm sorry if that offends you, but that's my opinion as someone who also does these things - even if only for a hobby - is that if I made that, I wouldn't consider it worth showing, and that's how I judge stuff. You got paid to do it - well done & good job. But don't expect it to exempt you from criticism; if anything it opens the floodgates because you're able to call yourself professional now.
Incidentally - Krogg destroyer also looks a lot like Battlefleet Gothic models IIRC.
