I like the unconventionality in a sense...
Maybe the engines in the side could be shorter and thinner and the legs could be attached to the bottom of the hull (as wide as possible)...
And the front more streamlined, the bottom extrusion taken out, dunno, something... and some less turrets on the top, maybe a few bigger ones. And perhaps an island (you know, the command tower of the carrier). They're kinda in the way of the landing where they are currently..
And just everybody will be pleased with the polycount and sense of balance- and who doesn't want turrets that would fire through each other for better than 120 degrees of arc?
And yes, we're being silly. It's an awesome sled... thing... but it doesn't make a lick of sense, and it's not exactly low-poly. That said, please don't take our commentary really seriously- we're just goofing off. Lord knows, I have made stuff that looked far worse...
I'd take the top turrets and convert them to a large rear mount flak cannon to balance the weight and keep everything logical. Oh, and that cannon would be able to fire at ground units effectively.
To be fair it's not like many of our other modelers aren't ever guilty either. Analise one of the units in nanoblobs some time if you feel like a bit of a laugh.
